# 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.
