Question

Q3:
The diameter of a wheel is 70cm. How many times the wheel will revolve in order
to cover a distance of 110m?
​

Answer 1

radius = diameter/2

= 70 cm/2

= 35cm

circumference of the circle =2×pie×r

=2×22/7×35cm

=2×22×5cm= 220cm

1 cm= 1/100m

220/100m= 2.2m

revolve order to cover a distance = 110/2.2

= 50
