Answer:
Step-by-step explanation:
Circumference =π×diameter
30π=π×diameter
Diameter=30π÷π
Diameter=30in
B. 30 inches
Reason:
The radius of the circle would be 15pi because 30pi divided by 2 would be 15pi (the formula for circumference is 2 x pi x radius). Diameter would be 2x the radius, so 15pi x 2 = diameter = 30
