Question 1063439: How many cubic feet of water are in the tower if it measures 20 feet high and has a radius of 7 feet? Use 3.14 for pi. can you explain every move to make so I will understand, where the 20 go, where the 7 go, and where the 3.14 go.

I am assuming a cylindrical tower, not conical.
The volume of a cylinder is pi*r^2h, the pi*r^2, coming from the end, which is circular, and the h which is the height.
The 7 goes into the radius, the 20 into the height.
V=3.14*7^2*20
V=3.14*49*20=3077.2 ft^3, the ft^3 being from ft^2 (r^2) * h (ft)
