Question

The diameter of a wheel is 14cm. Find how many times
the wheel will revolve in order to cover a distance of
22 km​

Answer 1

Step-by-step explanation:

Diameter of the wheel= 14cm

radius = 14/2 = 7

Circumference of the circle = 2 pi r

= 2*22/7*7

=44cm

circumference of the circle is 44cm

22km in cm= 2200000cm

total revolution required for completing 22 km

= 2200000/44

= 50000

Therefore, Total 50000 revolution are required for covering 22 km

Answer 2

Answer:

Step-by-step explanation:

Perimeter formula 2pie r same as pie diameter

22/7*14

Equals 44m

22km is equal to 22000m. the no. Of times the perimeter of the circle has to be repeated is 22000/44

Equals to 500
