A child pushes a playground merry-go-round so handle A moves to position B. The radius of the merry go round is 5 feet and the distance traveled by the handle along the arc from A to B is 4.5 feet. Find to the nearest degree, the measure of minor arc AB.
Use the sin function to solve for the central angle. Chord length = 2Rsin(c/2) where chord length =4.5 feet radius = 5 feet C= central angle Rearrange the formula to get the central angle and substitute all the given values Central angle = 53.49 degrees
