1.	of all lle UTIu9.The diameter of a garden roller is 1.4 m and itis 2 m long. Find the maximum area coveredby it in 50 revolutions?2A cvlindrical pillars.
Answer» Radius of a garden roller (r) = 1.4 / 2 = 0.7 m and length of the garden roller (h) = 2 m ∴Curved surface area of garden roller = 2πrh . So, the area levelled of a garden roller in one revolution is 8.8 m2. Now, area levelled of a garden in 50 revolutions = 8.8 x 5= 440m2

Answer»

Radius of a garden roller (r) = 1.4 / 2 = 0.7 m

and length of the garden roller (h) = 2 m

∴Curved surface area of garden roller = 2πrh .

So, the area levelled of a garden roller in one revolution is 8.8 m2.

Now, area levelled of a garden in 50 revolutions = 8.8 x 5= 440m2
