Circle A has a diameter of 8 inches, a circumference of 25.12 inches, and an area of 50.24 square inches. The diameter of circle B is 3 inches, the circumference is 9.42 inches, and the area is 7.065 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)
Part C: What observation can you make about the value of pi for circles A and B? (2 points)

Best ResponseYou've already chosen the best response.1circle A: circumference: 25.12 inches. thus 2*4*pi=25.12 pi=3.14 area: pi*4^2=50.24 pi=50.24/16=3.14
