Question

The Darnells are having a swimming pool installed. The pool has a radius of 14 feet and a height of 4 feet. What is the volume of the pool?

Answer 1

So a circular pool will be in the shape of a cylinder. and the formula for finding the area of a cylinder is
`2 \pi r^(2) +2 \pi rh` . r=radius, h=height. If we put the numbers into the equation it is
`2 \pi 14^(2) +2 \pi 14(4).` .14 squared is 196 and 4*14= 56. So our equation is now
`2 \pi (196)+2 \pi (56)`. 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(196)+6.283(56). Just multiply them. 1231.504+351.858= 1583.362 is your final answer.
