Question

how much cloth is requried to set up a conical
shaped tent with height 4m and radius 10.5m.

Answer 1

surface area of tent i.e cone is π.r.l

given values, radius (r) = 10.5m
height (l) = 4m

therefore surface area of cone = 22/7*10.5*4
Cloth required to set up a conical shaped tent  = 132m²

Answer 2

Radius (r) = 10.5
Height (l) = 4m

Surface area  of a cone =  $\pi$ x r x l
                                = 22/7 x 10.5 x 4
                                = 132 m²
Thus cloth required to set up a conical shaped tent = 132 m²
