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
Answer:
The answer is 3
Step-by-step explanation:
