The windshield wipers of a car is 24 inches long. How many inches will the tip of the wiper trace out in 1/4 revolution.
» Measuring 1/4 revolution is just 1/4 of the circle's circumference. Let's imagine the wiper as the radius measuring 24in. Let us find the circumference with the radius of 24in.
» Determine the fourths of its circumference that it traces the 1/4 of a revolution.
» Let 3.14 be the approximate value of pi.
The measure of the tip of the wiper that traced out 1/4 of the revolution is about 37.68in.
