HOW MANY TIMES A WHEEL OF RADIUS 28 CM MUST ROTATE TO GO 352M ?? (TAKE PI =22/7)

 total distance=352m

raidus of wheel=28m

circumference of wheel = 2 pie r

=2 x 22/7 x r

=2 x 22/7 x 28

=2 x 22 x 4

=8 x 22

=176cm

distance covered in one rotation=176cm

no.of rotation of a wheel = total distance/distance covered in one rotation

=35200/176

=17600/88

=4400/22

=200/1

=200

hope this helps

Circumference of the circle= 2 x 22/7 x radius

                                                 =  2 x 22/7 x 28cm

                                                 =176cm

Distance to be covered= 352m = 35200cm

Total number of rotations required=35200/176

                                                              =200

Therefore,200 rotations are required to cover the distance of 352m.

 radius of the wheel=28cm

circumference=2x22/7x28=176cm

distance to be covered=352x100cm=35200cm

no of rotations to cover 176cm=1

therefore,number of rotations  35200cm=1/176x35200=200
