Using the figure at the right, match the measure with its approximation value (hint:C=2πr, t=6/350•2πr) 1.the total arm and blade of a single windshield wiper was 10 in. long and rotated back and forth through an angle of 95°.The shaded region in the figure is the portion of the windshield cleaned by the 7-inch wiper blade. What is the area of the region cleaned?
2.the pendulum on the grandfather's clock swings from side yo side once every second. If the length of the pendulum is 4 feet and the angle through which it swings is 20°.Find the total distance travelled in 1 minute by the tip of the pendulum on the grandfather's clock.​
