-Dominant- [34]

Given

Your family has a circular swimming pool.

The radius of the pool is 9 feet and and its depth is 4 feet.

Find out the volume of the pool.

To proof

As depth is given in the question that means the shape of the  swimming pool

is cylinder.

Formula

Volume\ of\ cylinder = \pi r^{2}h

where r = radius

h = height

now

radius of the pool is 9 feet and and its depth is 4 feet.

put all the values in the above equation

we get

= \pi\times 9^{2}\times 4

use 3.14 to approximate pi

= 3.14\times 9\times9\times4

we get

= 1017.4 ( approx )feet²

Hence proved
