Question

diameter of a wheel is 2.1 m then to complete 3.3 km distance hoe many revolutions of the wheel would it have to take??

Answer 1

$diameter = 2.1m \\ circumference = \pi \times d \\ \frac{22}{7} \times 2.1m = 6.6m \\ distace = 3.3km \\ = 3.3 \times 1000m \\ = 3300m \\ number \: of \: revolution = \frac{distance}{circumference \: of \: wheel } \\ = \frac{3300m}{6.6m } = 500$
