Question 703325
m of angle ACB = 120 degrees; length of arc AB = 9 feet, find the circumference.
------------
120 degs is 1/3 of the circle.  AB = 1/3 of the circumference.
C = 9*3 = 27 feet
==============================
and

circumference = 120 centimeters, length of arc AB = 12 centimeters. Find measurement of central angle DCE.
----------------------
12 is 1/10 of the circumference
Angle = 1/10 of 360 degs
Angle = 36 degs
