Question

Circle X has a circumference of 72π.what is the diameter of circle X?

Answer 1

Answer:36 in

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

Answer 2

Answer: 72

Step-by-step explanation:

since the formula of circumference is C= Pi times the diameter, In some cases when they don't say what Pi is same thing here. So, you would put the diameter and the pi sign next to each other. So 72 is the diameter.
