The radius of a conical tent is 7 m and the height is 24 m . Calculate the length of the canvas used to make the tent if the width of the rectangular canvas is 4m ?

The radius of a conical tent is 7 m and the height is 24 m. What is the slant height?

The focal length of the concave lens is 7 m. Calculate the power of lens.

A tent is in the shape of a cylinder surmounted by a conical top. If the heigh and diameter of the cylinder part are 2.1 m and 4m. And slant heigh of the top is 2.8m, find the area of the canvas used for making the tent. Also find the cost of canves of the tent at the rate of Rs 500 per m^(2) .

4 person live in a conical tent whose slant height is 19 cm. If each person require 22 cm^(2) of the floor area, then find the height of the tent.

A tent is in the form of a cylinder surmounted by a cone having its diameter of the base equal to 24 m. The height of cylinder is 11 m and the vertex of the cone is 5m above the cylinder. Find the cost of making the tent, if the rate of canvas is 10 per m^(2)
