Derive the circumference of a circle from the following information: r = 13 m.

A. 26 m
B. 13 m
C. 26 PI m
D. 13 PI m

1 answer

C. 26 PI m

The formula to calculate the circumference of a circle is C = 2πr, where r is the radius of the circle. Plugging in the given radius of 13 m:

C = 2 * π * 13
C = 26π

Therefore, the circumference of the circle is 26π meters.
