Question

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.

Answer 1

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

Answer 2

Answer:

1017.36

Step-by-step explanation:

First off, the original answer is incorrect. Don't read it.

The first answer is partially correct.

3.14 × (9 ft)∧2 × 4 ft = 1,017.36 ft∧3
