Question

Find the distance of a wheel where the radius is 10 feet and it gives 15 rotations. How many inches did the wheel travel in those 15 rotations?

Answer 1

We will find the distance after 15 rotations by multiplying the perimeter of the circumference by 15, that is:

`d=15(2\pi r)\Rightarrow d=30\pi(10)\Rightarrow d=300\pi\Rightarrow d\approx941.48`

From this, we have that the wheel traveled approximately 941.48 feet.
