Question

Paul has a tack stuck in his four-wheeler tire. if the tire has a diameter of 36 inches, how far does the tack travel in 62° of rotation?

Answer 1

diameter of the wheel is 36"
so the redius will be 36/2 = 18"

we know that the circumference of a circle is equal to 2 x pi x r
2 x (22/7) X 18
this circumference will be the distance covered by the will after a rotation of 180 degree

now through unitary method you can easily find what would be the distance covered by the will after 62 degree rotation

I hope this answer will help you if so please mark my answer as brain list
