Shina designed her perfect wedding cake. She wants to have 3 layers with smooth
white frosting on the cake. The first layer will have a 24-inch diameter, the second
layer will have an 18-inch diameter and the top layer will have a 10-inch diameter.
Each layer will be 6-inches tall. How many square inches of frosting will show on the
surface of the cake? Hint: you will not frost the bottom of the cake.
