Answer 2

Answer:

5,940,000 m^2

Step-by-step explanation:

Diameter of roller = 63m

therefore, radius of roller = 63/2 = 31.5

Lenght of the roller = 100m

We know that,

CSA of roller= 2πrh

= 2 x 22/7 x 31.5 x 100

= 19,800 m^2

Number of revolutions completed = 300

Therefore, Area of playground= 19,800 x 300

= 5,940,000 m^2
