Circles, SM-Bank 034 MC A wheel on a bicycle has a diameter of 530 mm. The wheel turns 12 times. Approximately how many metres has the bicycle travelled? \(6\ \text{m}\) \(20\ \text{m}\) \(40\ \text{m}\) \(399\ \text{m}\) Show Answers Only \(B\) Show Worked Solution \(\text{Diameter}=530\ \text{mm}=0.530\ \text{m}\) \(\therefore\ \text{Distance}\) \(=12\times \text{circumference}\) \(=12\times \pi d\) \(=12\times \pi\times 0.530\) \(=19.9805\dots\) \(=20\ \text{m (nearest m)}\) \(\Rightarrow B\)
