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 .

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.

Apply the formula and do the calculation correctly you will get the solution .

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 .

As the plastic funnel was cut along its slant height so in order to find the radius of the sector so formed we need to find the slant height of the 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 .

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

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 .

Just find the slant height first and then go on to find the curved surface area .

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