## Homework Statement

Coverting Cord length to radians and the other problem is: A ball Radius = 12 CM, rolls 15 M, across the gym floor. Through what angle does the ball rotate?

We just started this today and im very confused by it. the other question is converting 11.6 CM Chord Length into Radians.

## Homework Equations

O=s/r

## The Attempt at a Solution

I dont know how to convert chord length to radians and on the next one I converted 15M to centimeters and then i plugged it into the formula doing 1500CM/12CM which gets me 125 Radians and then I did 125(180/3.14) and got 7165 Degrees which cannot be correct.
