Answer:

r = 5.97 cm

Explanation:

The area of the sector is given by the following equation:


A = r*S = 2\pi*r^(2)*(58)/(360)

Where:

r: is the radius

A: is the area

The radius is:


r = \sqrt{(A)/(2*\pi*58/360)} = \sqrt{(36.07 cm^(2))/(2*\pi*58/360)} = 5.97 cm

Therefore, the radius of Circle M is 5.97 cm.

I hope it helps you!
