The swimming pool that has a diameter of 20 feet and a depth of 4(1/2) feet. It cost about $0.75 per cubic foot to maintain the pool during summer. About how much does it cost for the maintain pool to be their ?
The pool is just the volume of a cylinder with a height of 4.5 ft. and radius of 10 ft.
So.......the volume =
pi * r^2 * h =
pi * [10]^2 * [4.5] = 450*pi ft^3
So, the total maintenance cost = cost per cubic ft * number of cubic ft. = .75 * 450*pi = about $1060.29
