Question

The circle below has center O, and it's radius is 7 in. Given that m

Answer 1

You have the next circunference:

As the angle in a circunference is 360: then angle in the rest of the circunference is 330º.

To find the length of the arc ACB you need to turn the angle in radians:

If 180º is π

$330º\cdot\frac{\pi}{180º}=\frac{330º}{180º}\pi=\frac{33}{18}\pi=\frac{11}{6}\pi$

You use the next formula to find the length of the arc ACB:
