@jim_thompson5910 Can you help me?

jimthompson5910 (jim_thompson5910):

the central angle APC is 180 - 60 = 120 degrees

jimthompson5910 (jim_thompson5910):

120 degrees is 120/360 = 1/3 of a full circle

jimthompson5910 (jim_thompson5910):

multiply 1/3 by the circumference of the circle to get your answer

OpenStudy (larryjo2):

Might sound like a dumb question but i forgot 1/3 of a circle is 120 right
