L(Slant height) = √ (r^{2 }+ h^{2})

Volume = ⅓ πr^{2}h

First of all find the height of the given cone by relating the given values to that of unknown , then find the curved surface area .

Relate the formula to find the volume of the tent to that of its actual volume given to us and then put all the known values to find the unknown .

In order to find the ratio between cylinder to that of the cone , we should compare the formula of cylinder to that of cone .

Relate the volume of the conical tent whose volume is given to us to the formula and put all the values into the formulae and work out the unknown term that is height by using the inverse problem .

L(Slant height) = √ (r^{2 }+ h^{2})

Volume = ⅓ πr^{2}h

In order to find the ratio between cylinder to that of the cone , we should compare the formula of cylinder to that of cone .

Do you remember that the volume of a given cone with same height and base radius is 1/3 of that of the volume of cylinder .

Find the volume of cubical solid and also find the volume of conical solid and then look for how many such conical solids can be made from such cube .

As the cone is made of a sector shaped metallic sheet so the length of the arc of the given metallic sheet will lie along the circumference of the cone so formed.
