What is the square feet of a 24 diameter drainage pipe?

Answer 1

I couldn't possible tell you! You haven't given enough measurements, but I will tell you the formula to figure out the volume of a cylinder. The volume of a cylinder is simply the area of the circular base times the cylinder's height. Volume of a cylinder = Pi x r^2 x h, or 3.14 x r-squared x h= v, where Pi = 3.14 r = radius of the base circle, and (in your case, the radius would be 12) h = height of the cylinder
