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
[tex]Volume\ of\ cylinder = \pi r^{2}h[/tex]
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
[tex]= \pi\times 9^{2}\times 4[/tex]
use 3.14 to approximate pi
[tex]= 3.14\times 9\times9\times4[/tex]
we get
= 1017.4 ( approx )feet²
Hence proved
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
