Find the internal curved surface area of the conical as well as the cylindrical potion so that we can find the cost of whitewashing the structure .

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.

By relating the given volume of the conical vessal to that of the other unknown quantities we can find out the diameter by using inverse operations .

Use the formula of volume of a cone.

Volume of a cone = ⅓ πr^{2}h

1000 litres = 1 m^{3}

In order to find the cloth needed to make the conical tent we need to find its curved surface area as the base of the tent is open .

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 .

In order to find the cloth needed to make the conical tent we need to find its curved surface area as the base of the tent is open .

Volume of cone = \\(\\frac{1}{3} \\pi r^2 h\\)

First of all find the radius of the given cone and then put the known values into the formula to work out the curved surface area of the given conical tent to calculate the cost of the tent so formed .
