Question

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

Answer 1

Choice C

The length of the circumference is 24π in

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
