Question

The radius of a wheel of a bus is 0.70m how many revolution it will cover in covering 22 km

Answer 1

Step-by-step explanation:

Given:

Radius of wheel=0.70m

since,

Circumference:

=2×22/7×0.70

=(2×22×7)÷7×100

=44÷100

=0.44m

=1 revolution

Therefore

No. of Revolutions

=22×1000÷0.44

=22000÷0.44

=50000

Answer 2

Answer:

Radius = 0.70m

perimeter = 2×22/7×0.70

=44×0.10

=4.40m

no. of revolution are= 22000m/4.40

=220000/44

= 5000
