Question

A circular ice rink is being built in town. Around the ice rink, a walkway will be built. The ice rink will have a diameter of 80 feet and the walkway will be 10 feet wide. What is the approximate area of the walkway?

Answer 1

To solve, you'd have to find the area of the big circle(including walk way) and minus the ice rink.

Area of the big circle =
`3.15(50)^(2)` = 7850
Area of ice rink =
`3.14(40)^(2)` = 5024
7850 - 5024 = 2826

The answer is about 2,826 square feet.
