Question

If an arc with a measure of 34 degrees has a length of 38pi inches, what is the circumference of the circle?

Answer 1

None of these answers are correct

Explanation:

arc length =0/360×2pir

38pi=34/360×2×pi×r

38=1496r/2520

cross multiply

1496r=38×2520

1496r=95760

divide both sides by 1496

1496r/1496=95760/1496

r=64.01

C=2pir

C=2×22/7×64.01

C=402.35in
