A bicycle tire has a radius that measures 12 inches. Which of the following

represents the circumference of the tire?

(a) 6 inches

(b) 127 inches

(c) 24īt inches

(d) 367 inches

Choice A

O

Choice B.

Choice C

Choice C

The length of the circumference is 24π in

Step-by-step explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 12in

π = pi

c = 2π * r

we replace with the known values

c = 2 * π * 12in

c = 24π in

The length of the circumference is 24π in
