Question

A wheel on John's bicycle is 1.1 m in diameter. John races the bicycle for 131 m. How many times does the wheel turn as the bicyde travels this distance?
Use the value 3.14 for m. Round your answer to the nearest tenth. Do not round any intermediate steps
Please show steps

Answer 1

Answer:

37.9 times

Step-by-step explanation:

Circumference of John's bicycle =

$2\pi \: r \\ = 2(3.14)(1.1 \div 2) \\ = 3.454m$

Total number of wheel turns =

$\frac{total \: distance \: travelled}{circumference \: of \: wheel} \\ = \frac{131}{3.454} \\ = 37.9 \: times \: (nearest \: tenth)$
