An arc of a circle is 3πm long, and it subtends an angle of 72° at the center of the circle. Find the radius of the circle.The radius of circle is______mthat is how it should be put as answer.

Using the arc length equation [tex] \frac{angle measure}{360} [/tex] x 2πr, you can solve for the radius. So, the radius of the circle is 7.5m.
