Question

the diameter of a wheel is28cm how many Revolution will it make to travel 352 m

Answer 1

1 rev =  perimeter of the circle

perimeter = 2$2\pi r$

= 2×22/7×14

=88cm

352 m = 35200cm

35200/88

= 400 revs

Answer 2

Hi !!! Here is your solution

We know that....

Diameter x pi = circumference. Distance/circumference = revolutions.  

So,

28 x 3.14 = 88 cm or 0.88 m

We convert this into meter because revolution is also given in meter that is 352 meter

352/.88 = 400 revolutions
