A circle has a radius of 48 millimeters. What is the length of the arc intercepted by a central angle that measures 3π4 radians? Express the answer in terms of π .
Assuming that you mean 3pi/4, we know that a circle has 2pi radians so 3pi/4 is 3/8 of it. The circumference is 96 mm so the length of the arrc is 36pi mm
