A cart has a wheel with a diameter of 24 cm. The wheel completes 120 full revolutions. How far does the cart travel? Give your answer in metres.

Step-by-step solution

1. The circumference of a wheel is $\pi \times$diameter: $\pi \times 24\text{ cm}=24\pi \text{ cm}$.
2. The cart travels $120$ revolutions, so the distance in centimetres is $120\times 24\pi =2880\pi$ cm.
3. Convert centimetres to metres by dividing by 100: $\frac{2880\pi }{100}=28.8\pi$ metres.

Concept tested: Distance = circumference × number of revolutions
