Question

a road roller of diameter 1.75 m and length how much ground can be pressed in 200 revolutions​

Answer 1

Distance covered by 1 roll = Circumference of roller

Circumference= diameter*22/7

=1.75*22/7

=5.5m

Ground covered in 200 rolls= 5.5*200

=1100m

Answer 2

The distance covered in 200 revolution by the roller is 1100 m.

Step-by-step explanation:

Given : A road roller of diameter 1.75 m and length.

To find : How much ground can be pressed in 200 revolutions​ ?

Solution :

A road roller of diameter 1.75 m.

Distance covered by the roller is equal to the circumference of the roller.

So, the circumference of the roller is $C=\pi d$

$C=\frac{22}{7}\times 1.75$

$C=5.5\ m$

The distance covered in 1 revolution by the roller = 5.5 m

The distance covered in 200 revolution by the roller =$5.5\times 200$  m

The distance covered in 200 revolution by the roller = 1100  m
