Volume of a Cone. The volume of a cone is equal to one-third the product of the area of the base and the height. It is given by the formula: where r is the radius of the base and h is the perpendicular height of the cone. Worksheet to calculate the volume of cones. Example: Calculate the volume of a cone if the height is 12 cm and the radius is 7 cm.
Find the volume of cylinders. Cylinders are tubes, where the top and bottom are circles. To find volume of a cylinder, use the equation V = pi x r 2 x h. Where pi = 3.14, r is the radius of the top circle, and h is the height. To find the volume of a cone, or pyramid with a circle for the bottom, use the same equation time 1/3.
