Question

The radius of a wheel of a bus is 0.70m. How many revolutions will it make in covering 22 km​

Answer 1

Answer:

Answer is 33 revolutions

Step-by-step explanation:

first we have to find its circumference, which is πr²

so, π = 22/7 or 3.14

, r = 0.70m

then, r²= 0.49

so, 3.14 × 0.49 = 1.54m²

1.54m² is the circumference of the wheel

then multiply with the distance

that is 22km

so 22×1.54 = 33.88.

so the no. of revolutions the wheel will take in 22 km is 33.88 revolutions
