Given radius =28 cm
area of the wheel(as it is a circle)=2πr
                                                     =2×(22÷7)×28=176cm
as it must rotate 352m which is given meter's we need to convert it in cm
                                      35200

hence no of time it rotates=35200÷176=200times

We need to calculate the circumference of this wheel as circle not the area

Radius of wheel=28 cm
distance= 352 m

circumference of circle = 2*22/7*28 = 176 cm
let convert centimeter into meter = 176/100 = 1.76 m

the wheel must rotate to go 352 m = 352/1.76 = 200 times
