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

(A) 6pi inches. (B) 12pi inches (C) 24pi inches (D) 36pi inches

C) 24pi inches

Step-by-step explanation:

In geometry, the circumference of a circle is the distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment. Since a circle is the edge of a disk, circumference is a special case of perimeter.

Formula:

C = 2 (pi) r

So: C = 2 (pi) 12 OR 24pi inches.

This means your answer is C.

(c) 24 pi inches.

Step-by-step explanation:

The Circumference is two times the size of the radius.

12*2=24
