Answer:

area : 551 m, r = 7 m

wastage :1m^2

as area of cone − 1/2 × base × height

551= 1/2 × 7 × height

=157.4m = height

Volume of cone = 1/3 πr^2 =h

= 1/3 × 22/7 × 7/7 × 157.4 × 1

=164.89

Given :

area : 551 m,

r = 7 m

wastage :1 m²

as area of cone = 1/2 × base × height

⟹551= 1/2 ×7×height

⟹ 157.4m = height

Volume of cone = 1/3 × πr² × h

⟹1/3 × 22/7 × 7/7 × 157.4 × 1

⟹164.89m²
