Conical tent has circular floor
àrea of floor = 154 m²
πr² = 154m²
r² = 154m²/22/7
r² = 154m²×7/22
r² = 7m²×7
r² = 49m²
r = 7m
In tent we don't put the canvas on the floor
slope height = l = ?
l² = h²+r²
l = √h²+r²
l = √576+49
l = √625
l = 5m
Curved surface area of cone = πrl
CSA = 22/7×7×5
CSA = 22×5
CSA = 110 m²
110 square metre canvas needed to make a conical tent
