A circle has a radius of 10. An arc in this circle

has a central angle of 72°

What is the length of the arc?

Either enter an exact answer in terms of tror

use 3.14 for and enter your answer as a

decimal.

Answer: The answer is 20 pi over 5

Step-by-step explanation:

You start by finding the circumference which you would get 20 pi by doing 2 times pi times your radius which is 10 then you find the fraction of the circle using the central angle which is 1/5 then you multiply 1/5 by 20 pi which you would put over 1 which then gives you 20 pi over 5
