Radius, R = 28/2 = 14 cm = 0.14 m
Circumference = 2π R
= 2 × 22/7 × .14
= 44 × 0.02
= 0.88 m
No. of revolution=total distance travelled/ circumference
= 352/0.88 = 400
Hence, no of revolution are = 400
Hope it may help you !!!!!

the area of the circle wheel = pi r² ( the radius = 28/2=14)
= 22/7 * 14*14= 616 cm²
revolutions = 616* 325
= 200200 revolutions
