Central Angles

Question

The diameter of a circle is 120 meters. The circumference of the circle is 377 meters and the area is 11,309 m^2. Find the measure of a central angle in degrees and in radians. 

Answer 1

120pi = about 377 meters

pi(60^2) = about 11310 square meters rounded to nearest integer (not 11309)

central angle = 360 degrees = 2pi radians
