this relation between arc length and the the radius would be helpful s=rtheta

OpenStudy (xapproachesinfinity):

you have s and you have the angle theta just plug them in and solve for r

OpenStudy (anonymous):

uh

OpenStudy (anonymous):

I don't get it

The formula is \(s = r\theta\), so just plug in values and solve for r.
