Substitute this formula into the volume formula, and you get V = (pi) r^2 (h). For a cylinder that's three inches tall and has a base with a radius of five inches, here's how you calculate volume: V = (pi) r^2 (h) V = () (5^2) (3) V = () (25) (3) V = cubic inches Spheres. The formula for the volume of a sphere is V = 4/3 (pi) r^3.

For example, the volume of a rectangular prism is measured as its length times width times height. In math language, V=lwh. The volume of a cylinder is π times the radius squared times the height of the cylinder, or V=πr 2 h. The volume of a cone is 1/3 πr 2 h, very similar to the formula of the volume of a cylinder. The volume of a pyramid is 1/3 lwh, which is similar to the formula for the volume of a . Math homework help.
