## anonymous 5 years ago to find arc length is it the degree/360*2*pi*r?

1. anonymous

arclength s = r * theta

To convert from degrees to radians:$\theta \times \frac{\pi}{180}.$ From radians to degrees, you instead multiply by 180/pi. $\theta = \frac{s}{r}$ where theta is the angle in radians, s is the arc length, and r is the radius. Solve for whatever variable you need, and out comes your value.
