Answer 2

It will cover 264m in 200 revolutions.

Given:

a diameter of A wheel of a car is 42 cm

To find:

how much distance will it cover in 200 revolutions

Solution:

First, we will calculate the radius of the wheel

Radius = Diameter/2

= 42/2 = 21

Now, we will calculate the perimeter of the wheel because the distance covered in one revolution is the perimeter of the wheel

Perimeter = 2 * π *  radius of wheel

= 2 * 22/7 * 21

= 2 * 22 * 3

= 132 cm

Distance covered in one revolution = 132 cm

Distance covered in 200 revolution = 132 * 200

= 26400 cm

1 cm = 1/100m

26400 cm = 26400/100 = 264m

Hence, the answer is 264m
