The volume of a cylinder refers to the amount of space the cylinder occupies. The volume of a cylinder is found by multiplying the area of the cylinder base by its height.
The formula to find the area of the circular base of a cylinder is Pi, approximately 3.142, multiplied by the squared radius of the circular base. The units used to measure the radius and height of the cylinder need to be the same. Converting the units is necessary if they don't match up.
The radius is found by drawing a line segment from the center of the circle out to perimeter.
