Game Shows Each game show wheel shown is divided into congruent sections. Find the measure of each arc.
36. 37. 38.
In Exercises 39 and 40, use the following information.
Sprinkler A water sprinkler covers the area shown in the figure.
58
It moves through the covered area at a rate of about 5o per second.
39. What is the measure of the arc covered by the sprinkler?
40. If the sprinkler starts at the far left position, how long will it take for the sprinkler to reach the far right position?
