Question 390645
A circle has radius of 5cm. 
What us the length of the arc described ( or outlined) by an angle of 5 pie/3 radians? 9 gives the answer as a simple decimal number to 2 dec. places)
---
arc length = radius*theta where theta is measured in radians.
----------------
Your Problem:
arc length = 5*[(5/3)pi] cm = (25/3)pi cm = 26.18 cm
