Question

Find the volume of a given solid

object where the radius of base
is 7 cm and height is 12 cm.​

Answer 1

Note: Consider the solid object is a cylinder because the radius of base and height of the solid is given.

Given:

Radius of base = 7 cm

Height = 12 cm

To find:

The volume of the given solid.

Solution:

The volume of a cylinder is:

`V=\pi r^2h`

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

Putting
`r=7,h=12,\pi=(22)/(7)` in the above formula, we get

`V=(22)/(7)*(7)^2* (12)`

`V=22* 7* 12`

`V=1848`

Therefore, the volume of the given solid is 1848 sq. cm.
