Question

What is the circumference of a 12-inch diameter pizza? Leave the answer in terms of ?.

Answer 1

Answer:

C = 37.7 inches

Step-by-step explanation:

You are looking for the circumference.

Formula for the circumference-> C=2πr

variables:

c = circumference

r = radius

You have the diameter, which is 12 inches. Radius is half of the diameter. which means r is half of 12 (aka 6).

put the radius where the variable is in the formula.

C=2π(6)

you now have enough information to solve for circumference.

C = 2 * π * 6

C = 37.7
