Question

Find the volume of the cylinder whose radius is 3cms and heightis5cms

Answer 1

Given,

Radius of the Cylinder = 3cm

Height of the Cylinder = 5cm

We know that,

Volume of Cylinder = πr²h

==> 22/7 × 3 × 3 × 5

==> 22/7 × 9 × 5

==> 22/7 × 45

==> 990/7

==> 141.42 cm³

Therefore, the volume of Cylinder is 141.43cm³.

Answer 2

QUESTION :-

Find the volume of the cylinder whose radius is 3cms and height is 5cm.

GIVEN :-

• r = 3cm

• h = 5cm

Find :-

• volume of cylinder.

SOLUTION :-

$\rightarrow$ $\rm{Volume\: of \:cylinder = \:πr^2h}$

$\rightarrow$ $\rm{ Volume \: of \: cylinder = \:3.14 × (3)^2 × 5}$

$\rightarrow$ $\rm{ Volume \: of \: cylinder = 3.14 × 9 × 5}$

$\rightarrow$ $\rm{\boxed{ Volume \: of \: cylinder = 141.3cm^3}}$

Hence, the volume of cylinder is 141.3cm³.
