The wheel of an engine turns 350 times round its axle to cover a distance of 1.76 km. The diameter of the wheel is
Correct Answer: √3 cm
Explanation:
Distance covered in 1 round
= (Total Distance) / (Total round)
= (1.76 x 1000)/350
= 176/35 m ∴ 2πr = (1.76 x 100) / 35 cm
2π = Diameter = 17600 x 7/22 x 35 = 160 cm
