Question 923695: Fomd the length of the arc, s, on a circle of radius r intercepted by a central angle theta. Express arc length in terms of pi to two decimal places.
r=18ft central angle = 345 degrees.
I always come out with 23pi/12, but mymathlab says it's wrong. I don't get it please help?

Fomd the length of the arc, s, on a circle of radius r intercepted by a central angle theta. Express arc length in terms of pi to two decimal places.
r=18ft central angle = 345 degrees.
--------
angle = 345 degs = 23pi/12 radians.
Arc length = r*angle = 18*23pi/12 ft
= 34.5*pi feet
