Question

Find the volume of a given solidobject where the radius of baseis 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 $r=7,h=12,\pi=\dfrac{22}{7}$ in the above formula, we get

$V=\dfrac{22}{7}\times(7)^2\times (12)$

$V=22\times 7\times 12$

$V=1848$

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