9. A wheel has a radius of 9 inches and
travels as it spins. How far does the
wheel travel in one revolution? Show your
work. Use 3.14 for n and round to the
nearest inch,

Answer 1

57inches

Explanation:

In order to determine how far the wheel travels, we will have to find the circumference of the wheel. This is expressed as;

Circumference of the wheel = 2πr

r is the radius of the wheel = 9in

Substitute

Circumference of the wheel = 2(3.14)(9)

Circumference of the wheel = 56.52inches

Hence the wheel travels 57inches to the nearest inch
