Could someone please help me? calculate the volume in cu. ft of a section of drainage pipe that measures 8 feet in lenght and 24 inches in diameter (all measurements has to be in the same units and be careful that you distinguish between diameter and area when using this formula) someone please please help me. thanks

im assuming the pipe is a cylinder. The equation for volume for a cylinder is:

length * area of base

to find the area of the base just do

pi * radius (in this case 12 inches or 1 foot)^2 (that means square the radius)

I would recomend changing all units to feet since the answer needs to be in feet, otherwise you might confuse yourself.
