Step-by-step explanation:
The formula for circumference is: C = 2πr
π = 3.14
r = radius.
The Circumference given to us is 72π. Plug in 72π for C
72π = 2πr
Isolate the variable, r. Divide 2 and π from both sides
(72π)/2π = (2πr)/2π
r = (72π)/2π
r = 36
36 in. is your answer

Set up an system:
x+y=52
x=y-2
Substitute in:
(y-2)+y=52
2y-2=52
2y=54
y=27
27-2=25
The answers are 27 and 25
