Answer 1

Answer: 1) 530.66 ft^2

Step-by-step explanation:

You need to find the area of the circles.

They gave you the formula to find them which is

Area = Pi * R^2    //// Pi times Radius squared will give you the area.

For example, the radius of the 1st question is 13ft. We use it with the formula given.

A = 3.14 * 13^2  /// 13 squared is just 13 x 13 = 169

A = 3.14 * 169   /// Now multiply Pi times 169

A = 530.66      /// Thats your answer.

530.66 ft^2
