Exercise 90 Page 635

Multiply the area of the top layer of the cake by the cake's height.

About 97.5 in.^3

The slice is a sector of a circle with a diameter of 14 inches. If we multiply the area of the sector with its central angle divided by 360^(∘), we can find the area of the top layer.

A=(7)^2π (38^(∘)/360^(∘)) ≈ 16.25 in.^2 To find the volume of the birthday cake we have to multiply the area of the top layer of the cake by the cake's height. V=16.25(6)≈ 97.5 in.^3
