Question

Chris is making a poster for Bike Safety Week. The diameter of circle A is 12 in. If the area of circle B is the area of circle A, what is the area of circle B? (Use 3.14 for .)

Answer 1

The area of A and B is the same.
The formula for getting a circus area is Area = Pie Radius Squared. The diameter is double the radius. 12 ÷ 2 = 6. Let's plug that in. 6 • 3.14 = 18.84. Square that and you get 354.9456. The are of circle B is 354.9456
