Answered by pprajwala24

Answer:

Since it takes 500 complete revolutions to move once over to level a playground, the area of the playground will be equal to 500 times the curved surface area of the roller. Let the radius and height of the cylinder are 'r' and 'h' respectively. Thus, area of the playground = 1584 m².
