Final: The Clay Cone
Part of the Surface Area & Volume section of Coddy's Geometry journey. Lesson 58 of 62.
A potter makes a solid clay cone. Its base has radius 4, and when it is glazed all over, base included, the glaze covers 36π square centimetres. The potter wants to know how much clay the cone holds.
The figure gives the radius and the surface area. Neither the slant height nor the height is labelled.
Challenge
The clay cone has radius 4 and surface area 36π. Find its volume, then press Check.
