Question

The diameter of the wheel is 35cm how much distance will it cover in 1000 revolution

Answer 1

Given,

Diameter = 35 cm
Radius = d/2
= 35/2
= 17.5 cm

Distance covered in 1 revolution = 2πr
= 2 * 22/7 * 17.5
= 110 cm

Distance covered in 1000 revolution = 1000 * 110
= 110000 cm
= 1100 m
= 1.1 km Ans.

Ans.) It will cover 1.1 km in 1000 revolution.

Answer 2

Radius = 35/2 cm

Distance covered in one revolution = Circumference of the circle
= 2πr
= 2×(22/7)×(35/2)
= 22×5
= 110 cm

Distance covered in 1000 revolution
= 110×1000
= 110000 cm
= 1100 m
= 1.1 km
