Question

please tell me answer of this question ​

Answer 1

given radius of circle = 28cm

so it's circumference = 2πr

= 2 × 22/7 × 28

= 2× 22 × 4

= 176 cm

distance needs to be covered by wheel = 352m

= 352 × 100

= 35200cm

so no. of rotations

= distance need to be covered ÷ circumference of the wheel

= 35200 ÷ 176

= 200

so 200 rotations is required
