Answer:

Solution :-

we know that,

Radius = (Diameter/2) .

Slant height = [Radius² + Height²]

CSA of cone = π * radius * slant height .

Base area of cone = π * (radius)² .

TSA of cone = CSA + Base Area.

Volume of cone = (1/3) * π * (radius)² * height .

Answer (iii) :-

→ Area of the floor = (14/2) = 7 m.

→ Cloth used for floor = Base Area of conical tent = π * (radius)² = (22/7) * 7 * 7 = 154 m² (d) (Ans.)

Answer (v) :-

→ Slant height of tent = √(r² + h²) = √(7² + 10²) = √(49 + 100) = √(149) ≈ 12.2 m (b) (Ans.)

Answer (i) :-

→ cloth was used for the floor = Total cloth - CSA of conical tent = 300 - {(22/7) * 7 * 12.2} = 300 - 268.4 = 31.6 m² (a) (Ans.)

Answer (iv) :-

→ T.S.A of the tent = CSA + Base Area = 268.4 + 154 = 422.4 m². (b) (Ans.)

Answer (ii) :-

→ Volume of the tent = (1/3) * (22/7) * (7 * 7) * 10 = (1540/3) ≈ 513.3 m³ (c) (Ans.)

Step-by-step explanation:

we know that,

Radius = (Diameter/2) .

Slant height = [Radius² + Height²]

CSA of cone = π * radius * slant height .

Base area of cone = π * (radius)² .

TSA of cone = CSA + Base Area.

Volume of cone = (1/3) * π * (radius)² * height .

Answer (iii) :-

→ Area of the floor = (14/2) = 7 m.

→ Cloth used for floor = Base Area of conical tent = π * (radius)² = (22/7) * 7 * 7 = 154 m² (d) (Ans.)

Answer (v) :-

→ Slant height of tent = √(r² + h²) = √(7² + 10²) = √(49 + 100) = √(149) ≈ 12.2 m (b) (Ans.)

Answer (i) :-

→ cloth was used for the floor = Total cloth - CSA of conical tent = 300 - {(22/7) * 7 * 12.2} = 300 - 268.4 = 31.6 m² (a) (Ans.)

Answer (iv) :-

→ T.S.A of the tent = CSA + Base Area = 268.4 + 154 = 422.4 m². (b) (Ans.)
