Exercise 32 Page 610

Multiply the area of the sector with the length of the solid.

About 6.28 ft^3

Practice makes perfect

The solid is a sector of a circle with a radius of 2 feet. If we multiply the area of the sector with its central angle divided by 360^(∘), we can find the area of the sector.

A=(2)^2π (45^(∘)/360^(∘)) = π/2ft^2 To find the volume of the solid we have to multiply the area of the sector with the length of the solid. V= (π/2)(4)≈ 6.28 ft^3
