The volume of a cone with a base of radius R and a height h is πR 2 h/3. Working through the formula for the volumes of those two cones, that difference can be expressed as π/3R 2 (h - 512/h 2).

Hell, as part of earth, would have to be cone-shaped. Dante even gives an exact value of Earth's radius of 3,250 miles (it's actually 3,959 miles).

Example Calculate the volume and surface area of a football with a radius of 12 cm. Volume = 4 3 π r 3 = 4 3 × π × 12 3 = 7, 238.2 cm 3 In the exam Volume = 4 3 π r 3 is given on the formula ...
