Question

A diagram of a hockey rink is shown below. The diameter of the middle circle is 30 Feet. What is the area of the middle circle? Use 3.4 for

Answer 1

The formula of the area of the circle is 
Area = pi * (d/2)^2

So using the formula,
Area = 3.14 * (30/2)^2
Area = 3.14 * 15^2
Area = 706.5 ft^2

So the area of the hockey rink is 706.5 ft^2
