Question

achha thik hai aashi sorry for ur inconvenience​

Answer 1

Radius of the wheel= 28cm

Circumference= 2\pi r=2\times\frac{22}{7}\times28=176cm2πr=2×722×28=176cm

Number of rotations made by the wheel in going 352m or 35200cm =\frac{35200}{176}=200=17635200=200

Hence, the required number of rotation= 200
