Question

Wheel diameter 56cm total distance covered 2.2 km find number of rotations

Answer 1

$diameter \: \: d = 56 \: cm \\ perimeter = \pi \times d = \frac{22}{7} \times 56 = 176 \: cm \\ distance \: covered = 2.2 \: km = 220000 \: cm\\ number \: of \: rotations \\ = \frac{distance \: \: covered}{perimeter} \\ = \frac{220000}{176} = 1250$
