Question

aqar cover the distance of 27 km if the radius of its wheel is 30 cm how many times the wheel rotate to complete the distance​

Answer 1

Answer:

distance covered by the wheel = 27 km

Radius of the wheel = 30 cm

∴ 2πr

= 2 × 3.14 × 30

= 188. 4 cm => 188.4 / 10⁻⁵ = 0.001884 km

1 rotation = 2πr = 0.001884 km

∴ Total no. of rotations for 27 km = 27 ÷ 0.001884 km

                                                       = 14331 complete revolutions...
