2. A cylinder has a height of 15cm and a volume of 500cm. Calculate the radius of the cylinder.


Jawaban:

10.6

Penjelasan dengan langkah-langkah:

diketahui:

t = 15 cm

v = 500 cm

ditanya:

r= ?...

rumus:

[tex] {r}^{2} = \frac{v}{\pi.t} [/tex]

[tex] = \frac{500}{3.14 \times 15} [/tex]

5. a rocket in the shape of a cone is attached to a cylinder with the same base radius . the cone has a slant height of 15 m. the cylinder has a base diameter of 12 m and a height of 42 m . find the total surface area of the rocket . tolong buat Cara nya yaa thankyouu


Kinda like this hopefully:
The area of cone = phi.r.(slant) height = 3.14 x 6 x 15 = 286.6
the area of cylinder = 2 phi r h + ph r2 = 2 x 3.14 x 42 + 3.14 x 6 x 6 = 1695.56
the total surface area is .... 286.6 + 1695.56 = 1982.16

6. Q.A cylinder has a diameter of 20 cm and a height of 16 cm. Calculate areathe tube surface!​


Jawab:

Penjelasan dengan langkah-langkah:

An area the tube surface = 2πr (r + h)

diameter = 20

r = 20/2 = 10

h = 16

An area the tube surface = 2 (3,14) (10) (10 + 16)

An area the tube surface = 62,8 (26)

An area the tube surface = 1.632,8 cm²

Penjelasan dengan langkah-langkah:

Area Of The Tube surface = 2nr(r + h)Diametre = 20 cmr = D/2 = 20/2 = 10 cmheight = 16 cm

Maka,

= 2nr(r + h)

= 2(3,14)(10)(10 + 16)

= 6,28(10)(10 + 16)

= 62,8(26)

= 1.632,8cm^2

7. A right circular cylinder has a base of radius 14 cm and height 21 cm. Find:-(i) The Volume of the cylinder.(ii) Area of the curved surface._____________Note:- Need the solution as well as explanation in English. :)​


Cylinder volume = 12.936 cm³Cylinder surface area = 3.080 cm³

Preliminary

The tube (cylinder) is a shape that has a base and a circular base. The properties of the tube are as follows :

Has 2 sidesHas no corner point Has a curved plane

Completion Be discoveredRadius (r) = 14 cmHeight (h) = 21 cmAskedVolume Surface areaAnswer

(ⅰ) Volume = πr²h

= 22/7 × 14² × 21

= 22/7 × 196 × 21

= 22 × 28 × 21

= 12.936 cm³

(ⅱ) Surface area = 2πr (r + h)

= 2 × 22/7 × 14 × (14 + 21)

= 2 × 22 × 2 × (14 + 21)

= 88 × 35

= 3.080 cm²

Penjelasan dengan langkah-langkah:

Stated: Circular cylinder has a base of radius 14cm and the given height is 21cm

To Attain: Volume of cylinder with Area of curved surface

⠀⠀⠀⠀⠀⠀⠀⠀__________________

❍ In this Question, It is concluded that circular cylinder has a base of radius 14cm and the concluded height is 21cm..

First, We will find out the the volume of cylinder by using the appropriate formula of cylinder.. Also, we will take pi as 22/7 because it is not mention that which value of formula we have to choose..

Where -

r = radiush = height

❍ Volume of cylinder = πr²h

[tex]\begin{gathered}\dashrightarrow\sf{Volume = \pi \times {r}^{2} \times height}\\\\\\ \dashrightarrow\sf{Volume = \dfrac{22}{\cancel{7}}\times \cancel {14} \times 14 \times 21}\\\\\\ \dashrightarrow \sf{Volume \: = 22 \times 14 \times 21} \\\\\\ \dashrightarrow \underline {\sf {\pink{Volume \: = 12.936 \:{cm}^{3} }}}\end{gathered}[/tex]

Now -

❍ We have to find the surface area of cylinder by using the formula 2πr (r+h).. Let's solve it..

[tex]\begin{gathered}\dashrightarrow\sf{S.A = 2 \pi r (r + h) }\\\\\\ \dashrightarrow\sf{ S.A=2 \times \dfrac{22}{7}\times {14} (14 + 21)}\\\\\\ \dashrightarrow \sf{S.A\: = 2 \times 22 \times 2 \times 14(14 + 21)} \\\\\\ \dashrightarrow {\sf{S.A \: = 88 \times 35}} \\ \\ \\ \dashrightarrow \underline{\sf{\pink{S.A = 3.080 {cm}^{2} }}}\end{gathered}[/tex]

FinalAnswer-

Volume of cylinder is 12.936cm³ and surface area of cylinder is 3.080cm²

10. a cylinder and a cone of the same height 2r and the same base diameter 2r. A sphere has a diameter of 2r. Find the ratio of the volume of the cylinder to that of the cone and to that of the sphere


Jawab:

6:1:4

Penjelasan dengan langkah-langkah:

Volume of the cylinder = [tex]\pi r^{2}h=\pi r^{2}(2r)=2\pi r^{3}[/tex]

Volume of the cone = [tex]\frac{1}{3} \pi r^{2}h=\frac{1}{3} \pi r^{2}(2r)=\frac{2}{3} \pi r^{3}[/tex] and,

Volume of the sphere = [tex]\frac{4}{3} \pi r^{3}[/tex]

thus, the ratio of the volume of the cylinder to that of the cone and to that of the sphere are

Volume of the cylinder : Volume of the cone : Volume of the sphere

[tex]2\pi r^{3}:\frac{2}{3} \pi r^{3}:\frac{4}{3} \pi r^{3}\\=2:\frac{1}{3} : \frac{4}{3} \\=6:1:4 \\[/tex]  


11. A solid is made up of cone and a cylinder. The radius of the cylinder is 7 cm. If the height of the cylinder is 10 cm and the height of the solid is 16 cm, then the volume of the solid is...cm


Padat terdiri dari kerucut dan silinder. Jari-jari silinder adalah 7 cm. Jika tinggi silinder 10 cm dan tinggi padatannya 16 cm, maka volume padatannya adalah ... cm

r = 7 cm
t tabung = 10 cm
tinggi kerucut = 16-10 = 6 cm

volumenya adalah
= volume tabung + volume kerucut
= phi r^2 t + 1/3 phi r^2 t
= 22/7 x 7 x 7 x 10 + 1/3 x 22/7 x 7 x 7 x 6
= 1540 + 308
= 1840 cm^3


12. A measuring cylinder has a mass of 120 g when empty. When it contains 50 cm3 of a liquid, the total mass of the measuring cylinder and the liquid is 160 g. What is the density of the liquid?


Mass of cylinder (empty) = 120 gram

Mass of cylinder (with liquid) = 160 gram

Volume of liquid = 50 cm³

Density of the liquid (ρ) = ?

Answer:

Find the mass of liquid

With liquid - Empty

= 160 gram - 120 gram

= 40 gram

So, the mass of the liquid is 40 gram

Find the density of the liquid

[tex]\rho=\frac{mass}{Volume} \\\rho=\frac{40\ gr}{50\ cm^3} \\\rho=\frac{40}{50}\ gr/cm^3 \\\rho=\frac{4}{5}\ gr/cm^3 \\\boxed{\rho = 0,8\ gr/cm^3}\\or\\\boxed{\rho = 800\ gr/cm^3}\\[/tex]

Penjelasan dengan langkah-langkah:

Given that:

A cone is located inside a cylinder

base diameter (d) = 12 cmVcone = 345 cm³hcone = 1/3(hcylinder)Value of π ≈ 3,14

Find the volume of the cylinder (Vcylinder)

The equation for Vcone = (π×d²×h)/12

Find the height of the cone (hcone)

345 ≈ (3,14×12²×h)/12

345 ≈ (452,16×h)/12

452,16h ≈ 345×12

452,16h ≈ 4140

h ≈ 4140/452,16

hcone ≈ 9,15 cm

hcone = 1/3(hcylinder)

therefore

9,15 ≈ 1/3(hcylinder)

hcylinder ≈ 9,15 / (1/3)

hcylinder ≈ 9,15 × 3

hcylinder ≈ 27,45 cm

The equation for Vcylinder = (π×d²×h)/4

Therefore

Vcylinder ≈ (π×12²×27,45)/4 ≈

3.104,52 cm³ ✅

The volume of the cylinder located outside the cone is approximately 3.104,52 cubic centimetres, if not being rounded. ✅

18. 39. A solid cylinder A has a volume of 343 cm cubics.a) Find the volume of another cylinder B which has the same height but the base radius is one-third of the base radius of cylinder A.b) Cylinder B is melted and recast to form cubes of length 2 cm. Find the maximum number of cubes formed.​


Jawaban:

a) 38,111 cm²

b) 4

Penjelasan dengan langkah-langkah:

radius A = rA

radius B = rB

a) Volume A = 343 => Volum A = h × π × rA²

maka 343 = h × π × rA²

jika rB = ⅓ rA

maka Volum B = h × π × rB² => h × π × (⅓rA)² => h × π × 1/9 × rA²

343 = h × π × rA²

maka Volum B = h × π × rA² × 1/9 => 343 × 1/9 => 38,111 cm³

b) sisi kubus = 2 maka volumenya = 8 cm³

jumlah maksimal kubus yang terbentuk = 38/8 => 4 buah kubus
