Answer:
471.5
Explanation:
To find the cost to fill the pool, we first need to calculate the volume of the pool. The volume of a cylinder is given by the formula V = πr^2h, where r is the radius of the cylinder, h is the height and pi = 3.14
The diameter of the pool is 20 feet, so the radius is: r = 20/2 = 10 feet
The height of the pool is 6 feet (because the Smiths are only filling the pool to a depth of 6 feet)
So the volume of the pool is: V = π10^26 = 600*3.14 = 1884 cubic feet
The pool company charges $25 for every 40 cubic feet of chlorinated water, so to find the cost to fill the pool, we divide the volume of the pool by 40 and multiply by 25:
Cost = (1884/40)*25 = $471.5
Therefore, the cost to fill the pool is $471.5
