Answer:
Explanation:
Part A:
CIRCLE A : Circumference is (pi)(diameter) so if they give you the circumference (21.98), divide it by 7 which gives you 3.14.
CIRCLE B: 18.84/6 = 3.14
Part B:
CIRCLE A: Area is (pi)(radius^2) so if they give you the area (38.465), divide it by radius^2 (7/2 = 3.5^2 = 12.25) = 3.14
CIRCLE B: 28.26/(3^2) = 3.14
Part C:
The value of pi stays the same for circle A and B.
Hope this helps :)
