Question

The wheels on an adult sized 4-wheeler have a radius of 11 inches. What total distance will the wheels travel in one full rotation?

a
34.54 Inches

b
690.80 Inches

c
69.08 Inches

d
379.94 Inches

Answer 1

69.08 inches

Explanation:

We can plug in the known value into the equation for circumference:
`C = 2\pi r`

Using 3.14 as
`\pi` we get:

`C=69.08`

Now multiply the circumference by revolutions to get distance:

69.08 x 1 = 69.08

Note that the distance is in inches because the radius is in inches.

Answer 2

C. 69.08 inches

Explanation:

Find the distance the wheels will travel by finding the circumference of the wheel.

Use the circumference formula, C = 2
`\pi`r

Plug in 11 as r in the equation, and 3.14 as pi, then solve:

C = 2
`\pi`r

C = (2)(3.14)(11)

C = 69.08

So, the correct answer is C. 69.08 inches
