What is the length of the arc?
Either enter an exact answer in terms of 7 or use 3.14 for and enter your answer as a decimal.

Answer 1

Explanation:

Answer 2

Length of arc=4π

Step-by-step explanation:

Length of arc=¤/360 x 2xπxr

Where:

¤=72

r=10

Length of arc=72/360 x 2xπx10

Length of arc=0.2 x 20π

Length of arc=4π
