Spacing Between Teeth The length of an arc intercepted by a central angle of θ radians in a circle of radius r is r θ. The length of the chord, c, joining the endpoints of that arc is given by c = Find the actual distance between the tips of two adjacent teeth on a 12-in.-diameter carbide-tipped circular saw blade with 22 equally spaced teeth. Compare your answer with the length of a circular arc joining two adjacent teeth on a circle 12 in. in diameter. Round to the nearest thousandth.
