Answer 1

Step-by-step explanation:

ANSWER

Clearly the roller is a right circular cylinder of height h=120 cm

and radius of its base =r=42 cm

∴ area covered by the roller in one revolution = curved surface area of the roller 

           =2×22/7×42×120cm2=31680cm2

so, area covered by the roller is 500 revolution = (31680×500)cm2

                    =100×31680×500/100×100m2=1584m2

So the are of the playground is 1584m²
