Question

find the diameter of a wheel that makes 490 revolution in going a distance of 4 kilometre 4m

Answer 1

Answer:

Diameter = 2.6 m

Step-by-step explanation:

Distance=4 km 4 m = 4004 m

Number of revolutions = 490

Since 1 revolution consists of 1 complete circumference

therefore- 490 revolutions consists of 4004 m.

490 * Circumference = 4004 m

Circumference = $\frac{4004}{490}$ = π * diameter

$\frac{4004}{490}$ = $\pi$ * diameter

diameter = $\frac{\frac{4004}{490} }{\pi }$

diameter = 2.6 m
