Answer 2

Thanks for your question

Your required answer :

Given :

• Diameter = 2.5 m
• $So ,Radius = \frac{2.5}{2}$
• Length = 1.4 m

To find :

• We have to find how much area will cover in 7 revolutions .

Solution :

• Curved Surface Area of cylinder : 2πrh

$= 2 \times \frac{22}{7} \times \frac{2.5}{2} \times 1.4$

= 11 m²

We know that area covered by roller = Curved Surface Area

So :

• 7 × 11
• 77 m²
