Answer :

1) We have,

Area of canvas = 551 m^{2}

Area of canvas lost in wastage = 1 m^{2}

∴ Area of canvas used in making tent

= (551-1) m^{2} = 550 m^{2}

= Surface area of the cone = 550 m^{2}

We have,

*r* = radius of the base of the cone = 7 m

∴ Surface area = 550 m^{2} = π*rl* = 550

=×7×*l*=550 = *l* = 25 m

Let *h* be the height of the cone. Then,

*l*^{2} = *r*^{2}+*h*^{2} = *h* = = = 24 m

∴ Volume of the cone =

= m^{3} = 1232 m^{3}
