Question

Somebody please help me plsssss

Answer 1

Given:

The radius of the cylinder = 2 cm

Height of the cylinder = 5 cm

To find:

The volume of the cylinder.

Solution:

We know that, the volume of a cylinder is:

$V=\pi r^2h$

Where, r is the radius and h is the height of the cylinder.

Putting $r=2,h=5$ in the above formula, we get

$V=\pi (2)^2(5)$

$V=\pi (4)(5)$

$V=20\pi$

Therefore, the volume of the cylinder is $20\pi$ cubic cm and its approximate value is 62.832 cubic cm.
