The radius of a car wheel is 12 inches. How far will the car travel and 15 revolutions of the wheel?
1 answer:
R = 12 inches, the radius of the wheel.
The circumference of the wheel is
2πr = 2π(12) = 24π inches.
WHen the wheel makes 15 revolutions, the car will travel 15 times the circumference, which is
15*(24π) = 360π inches = 1131 inches.
