HEY ! FRIEND HERE IS THE ANSWER U R LOOKING FOR
Radius of the wheel = 28 cm
Distance covered by the wheel in one rotation = 2πr
= 2 × 22/7 × 28
= 176 cm
Distance to be covered = 352 m = 35200 cm
Number of rotations of the wheel to cover 35200 cm = 35200/176 = 200
HOPE IT HELPS !!!!
AND
MARK IT AS BRAINLIEST ......

let
r equal to 28
as we know that
circumference of circle is 2 pieR
now
2*22/7*28
176
now distance is 325 m so 32500cm
no.of rotation
32500/176
200 ans
