Question

What is the volume of cylinder with radius 7 cm and height 16 cm?

Answer 1

Answer:

V = πr^2h

= 22/7*7*7*16

= 22*7*16

= 2464cm^2

Answer 2

Question :-

What is a volume of a cylinder whose radius is 7cm and height is 16cm

Given :-

Radius of the cylinder = 7 cm

Height of the cylinder = 16 cm

Required to find :-

• Volume of the cylinder ?

Formula used :-

$\boxed{\mathrm{volume \; of \; cylinder = \pi {r}^{2} h }}$

Solution :-

Given :-

Radius of the cylinder = 7cm

Height of the cylinder = 16cm

He asked us to find the ,

Volume of the cylinder .

So,

Here we have to use a formula .

The formula is ,

$\boxed{\mathrm{volume \; of \; cylinder = \pi {r}^{2} h }}$

So,

Here let's take the pi value as 22/7 .

Hence,

$\longrightarrow{\tt{Volume \; of \; a \; cylinder = \dfrac{22}{7} \times 7 \times 7 \times 16 }}$

$\longrightarrow{\tt{Volume = 22 \times 7 \times 16 }}$

$\implies{\red{\underline{\tt{ Volume = 2,464 {cm}^{3}}}}}$

So,

If we take the pi value as 3.14

We get,

Volume = 2463.01

volume = 2464 cm³ ( approximately )

So,

$\large{\boxed{\mathsf{\therefore{Volume \; of \; a \; Cylinder = 2,464 {cm}^{3}}}}}$

points to remember :-

1. $\boxed{\mathrm{volume \; of \; cylinder = \pi {r}^{2} h }}$

Where,

• r = radius of the cylinder

• h = height of the cylinder
