## anonymous one year ago Describe the relationship between the radian measure of an angle, and a circle’s radius and circumference

1. anonymous

I think that the radius has something to do with finding the circumference of a circle

s = arc length theta is the angle in radians $\Large s = \frac{\text{angle in radians}}{2\pi \ \text{radians}}*(\text{circumference})$ $\Large s = \frac{\theta}{2\pi}*2*\pi*r$ $\Large s = \frac{\theta}{\cancel{2\pi}}*\cancel{2\pi}*r$ $\Large s = \theta*r$
