Volume of a Cylinder
A cylinder is a solid composed of two congruent circles parallel planes, their interiors and all the line segments parallel to the segment containing the centers of both circles with endpoints on the circular regions.
The volume of a 3-dimensional solid is the amount of space it occupies. Volume units are in units cubed (in3 , ft3 , cm3 , m3 , et cetera). Be sure that all of the measurements are in the same units before computing the volume.
The volume V of a cylinder with radius r is the area of the base B times the height h .
Example:
Find the volume of the cylinder shown. Round to the neatest cubic centimeter.
Solution
The formula for the volume of a cylinder is .
The radius of the cylinder is 8 cm and the height is 15 cm.
Substitute 8 for r and 15 for h in the formula 
.
Simplify.
Therefore, the volume of the cylinder is about 3016 cubic centimeters.
