Question

The wheels on Karen’s rollerblades each have a diameter of 5 cm. How far will the rollerblade travel in one turn of the wheel? Use a calculator and round your answer to the nearest tenth of a centimeter.

Answer 1

15.7

Explanation:

C = πd = 5π = 15.70796327… ≈ 15.7 cm

Answer 2

To find the distance in one turn of the wheel you have to find the circumference of the wheel.

Circumference = pi x d
= 3.14 x 5
= 15.7 cm

therefore the rollerblade wheel will travel 15.7 cm per rotation
