How many cubic feet in 16' circle by 4'?

Answer 1

First, find the area of the circle. If the diameter is 16, the radius is 8. Formula for area of circle is pi times radius squared. 8 squared (8x8) is 64. Multiply 64 times pi (3.14). That will give you the area of the circle. For a volume of a cylinder 4 feet deep, multiply the area of the circle times the depth- 4 feet. The answer is the number of cubic feet (Your answer should be a little larger than 800- but you should practice doing the math on your own. Good luck!)
