I believe the first quartile would be 24 and the third would be 8. Sorry if this wasn't correct. I haven't done this in a while.
Hope it helps
Part A:
Circumference = πd
Circle A: d = 7
7π = 21.98
π = 21.98/7 = 3.14
Circle B: d = 6
6π = 18.84
π = 3.14
Part B:
Area = πr^2
Circle A: r = 3.5
π3.5^2 = 38.465
12.25π = 38.465
π = 3.14
Circle B: r = 3
π3^2 = 28.26
9π = 28.26
π = 3.14
Part C: The value of π is the same in circles A and B
Step-by-step explanation:
area of the small = pi * r^2
area of the big = pi * (2*r)^2 = pi * 4* r^2= 4* area of small
-> ratio of small : big = 1: 4
