Question

A diameter of a wheel of a car 70 cm . How many revolution will in 1.5 km​

Answer 1

Answer:

Hola mate your answer below

Given:

Diameter = 70 cm

Radius = 70/2 = 35 cm

1. 5 Km = 150000 cm

Solution:

Circumference = 2πr

$\implies$ 2 x 22/7 x 35

$\implies$ = 220 cm

It means, 220 cm = 1 revolution

Then = 150000/ 220

$\implies$ = 168 revolution (approx)
