Question 167352
The length of arc AB is 6(pi)cm and the measurement of arc AB is 120 degrees. What is the diameter of the circle?
--------------------
The circle has 3(120) degrees
--------------------------------
The circumference of the circle is 3[6(pi)cm] = 18(pi)cm
----------------------
But circumference = (pi)d, where d is the diameter of the circle.
------------------------
EQUATION:
(pi)d = 18(pi)
d = 18 cm
