The radius of a circle is 20 kilometers. What is the angle measure of an arc 5π kilometers long? @ranga

anonymous · Answer

Length of an arc = n/360 (2pi)(radius)
5 pi = n/360 (2pi)(20)
5 pi = n/360 (40 pi)
1/8 = n/360
n = 45

so 45 degrees.

How about this one:
The radius of a circle is 2 centimeters. What is the length of a 45° arc?

anonymous · Answer

length of the arc = n/360 (2 pi)(radius)
length of the arc = 45/360 (2pi)(2)
Length of the arc = 1/8 (pi)
                               = pi/8

45/360 = 1/8
