Question

The diameter of a wheel is 70 cm how many times the wheel will revole in order to cover a distance of 110 m

Answer 1

11000/ (22/7 x 70) = 50 (ans)

Answer 2

Diameter=70
Radius= 70/2 =35cm

35 cm in metres = 0.35m

Now, Perimeter of wheel(circle)=
=2πr
=2π x 0.35
=0.7π
=0.7 x 22/7
=2.2 m

Now, No. of Revolution taken to complete 110m is = Distance/Perimeter

=110/2.2
=50 Times

Here is your Answer.........
