Quizplus · Accepted Answer

The formula for the circumference of a circle is C=2πr, where C is the circumference and r is the radius.

We are given that the circumference of the circle is 26π meters. So,

26π = 2πr

Divide both sides by 2π:

13 = r

Therefore, the radius of the circle is 13 meters.

The correct answer is D).
