The volume of a cylinder is the area of the base times the height. If the base has an 8 foot diameter, then it has a 4 foot radius. Hence the base has and area of . Multiply that by the 10 foot height, you get for the exact representation of the volume in cubic feet. If you need a numeric approximation, select an approximaton of to suit your need for precision and use your calculator to determine the appropriate approximation for .
