hiii!!!
here's ur answer...
given the diameter of the roller is 168cm. therefore radius of the roller = 168/2
= 84cm
height (length) of the roller is 240cm.
CSA of the roller = 2πrh
= 2×22/7×84×240
= 887040/7
= 126720cm²
in metre² = 126720/10000
= 12.672m²
total area of the playground if it takes 1000 revolutions to level it = 12.672×1000
= 12672m²
cost of levelling ₹30 per m² = 12672×30
= ₹380160
hope this helps..!
