Answer 2

Step-by-step explanation:

Step-by-step explanation:

Radius of conical tent = 7m

height of tent = 10m

width of convas = 2m

length of convas

Slant height of cone:-

l² = r² + h²

⠀⠀⠀⠀⠀l = √r² + h²

⠀⠀⠀⠀⠀➝ l = √7²+ 10²

⠀⠀⠀⠀⠀➝ l = √49 + 100

⠀⠀⠀⠀⠀➝ l = √149

⠀⠀⠀⠀⠀➝ l = 12.2 m

Total surface of cone = πrl

TSA of conical tent = 22/7 ×7 × 12.2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀➝ 22 × 12.2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀➝ 268.4 m²

Now,

Length of convas used to make the tent of width 2m

Area of tent = length × width

⠀⠀⠀⠀⠀➝ 268.4 = length × 2

⠀⠀⠀⠀⠀➝ 268.4/2 = length

⠀⠀⠀⠀⠀➝ 134.2m = length

So,

Length of convas used to make the tent of width 2m is 134.2 m
