You can use the degree measure of the central angle theta (the number of degrees you have gone around the circle) and the amount of radians you have gone around the circle
the equation for arc length using degrees and radians is: s(arc length) = r(xº)
r is not the radius length it is the length you have gone around the circle measured in terms of the radius
you need to know the central angle (degrees) and radians to figure out arc length without knowing the radius length

Step-by-step explanation:
Math to me is very complicated. I know that I need it in life, but when have you ever needed to find the square root of the distance from the sun to mars on a normal day-to-day basis? But jokes aside, I know that I do math without thinking about it. It is important, even for the jobs that you would think that you would NEVER need it (even English teachers do it, haha.) Overall, math is kinda iffy. In my opinion, you can't live with it, but you <u>really</u> can't live without it.

The idea is to swap each x and y, then solve for y to find the inverse.
