Answer:A is the correct answer
Part A)
circumference = PI * diameter
PI = circumference / diameter
PI = 21.98 / 7
PI = 3.14
PI = 18.84/6
PI = 3.14
Part B)
Area = PI * diameter^2 / 4
PI = 4 * Area / diam^2
PI = 4 * 38.465 / 7*7
PI = 153.86 / 49
PI = 3.14
Circle B
PI = 4 * Area / diam^2
PI = 4 * 28.26 / 6 * 6
PI = 113.04 / 36
PI = 3.14
Part C)
Conclusion - PI = 3.14 and is the same for both circles and is the same for EVERY circle.
