Shipping Stop Signs A manufacturer of stop signs ships 100 signs in a circular drum. Use the formula from Exercise 59 to find the radius of the inside of the circular drum, given that the length of an edge of the stop sign is 10 in. and the signs just fit as shown in the figure. Round to the nearest hundredth.

Exercise 59

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.
