Answer:
Rs 1856.25
Step-by-step explanation:
Area of playground = 750 × CSA of roller
= 750 × 2 × 22÷7 × 35 × 150
= 750 × 33000
= 24750000 cm^2
= 2475 m^2
Cost of leveling = 2475 × 0.75
= Rs 1856.25

curved Surface area of roller = 2×22/7×35×150 = 330 m²
now area covered by it in 750 revolutions = 750 ×330 =
247500 m²
cost of leveling 247500 m² = 247500/75 =3300 rs
