Asked by Allison

The diameter of a car's tire is 52 cm. While the car is being driven, the tire picks up a nail. How high above the ground will the nail be after the car has travelled 0.1 km?

can someone please explain how to solve this question?
Answered by Henry
C = 3.14 * 52 cm = 163.4 cm/rev.

0.1 km = 100 m = 10000 cm.

10000 cm / 163.4 cm/rev - 61.2 REVs.

d = 0.2 rev * 163.4 cm/rev = 32.7 cm
above ground.
