Solution
Diamter of the circular garden d = 49 m
Radius r = `"d"/2 = 49/2` m
Area of the circular garden = πr2 sq.units
= `22/7 xx 49/2 xx 49/2 "m"^2`
= 1,886.5 m2
Cost of levelling a m2 area = ₹ 150
∴ Cost of levelling 1886.5 m2 = ₹ 150 × 1886.5
= ₹ 2,82,975
Cost of levelling the flower garden = ₹ 2,82,975
