Your family has a circular swimming pool. the radius of the pool is 9 feet and and its depth is 4 feet. what is the volume of the pool? use 3.14 to approximate pi. round your answer to the nearest hundredth.

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

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

use 3.14 to approximate pi

we get

= 1017.4 ( approx )feet²

Hence proved

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
