I understand how to solve for the radius when the area of the sector shows ,for example, 8pi. When an example gives me: Given the sector area of 60.24in squared, and with an arc measurement of 90 degrees. Find the radius of the circle. There isn't a pi symbol after 60.24. How do I solve for this problem? Any help is appreciated! Thanks

multiply by 4 to find the total area of the circle. The area of a circle is (pi)r^2, so divide the total area above by pi. Finally, take the square root to find the answer Answer = 8.75785078 in Hope that helped
