Please help! :)

The circumference of the circle is 20 pi inches. What is the arc length of the shaded sector? Express the answer in terms of Pi.

Answer 1

Answer:A

Step-by-step explanation:2.5 Pi inches

Answer 2

Using the given equation:

Arc Length / 20PI = 45/360

Cross multiply:

Arc length * 360 = 20PI x 45

Arc length x 360 = 900PI

Divide both sides by 360:

Arc length = 900PI / 360

Arc Length = 2.5 PI inches.
