Wayne Thiebaud - Cakes

Wayne Thiebaud, Cakes, 1963

From the NGA Classroom - Sugary Shapes:

How can we calculate the amount of frosting on the cake?

First, try to estimate the amount of frosting you think it will take to ice the cake. Here are your choices: 12 square inches, 50 square inches, 98 square inches, or 222 square inches. This is how to figure the answer: The formula for the surface area of a cylinder is: 2(pi)(r2) + 2(pi)(r)(h), but the formula for the cake is: pi(r2) + 2(pi)(r)(h)
