Question

What is the length of the arc of a circle with radius 12 and central angle 3pi/4

Answer 1

9 pi

Explanation:

If the radius is 12, then the diameter would be 24 and the entire circle would be 24 pi.

24 times 3/8= 9

I used 3/8 because the unit circle has a circumference of 2pi so I divided it by 2.
