Question

In the given figure, a tent is in the shape of a cylinder surmounted by a conical top of same diameter. If the height and diameter of cylindrical part are 2.1 m and 3 m respectively and the slant height of conical part is 2.8 m, find the cost of canvas needed to make the tent if the canvas is available at the rate of Rs. 500 per sq.

Metre.[Use π 22 / 7]

Answer 1

Height of cylinder = 2.1 m

Radius of cylinder = radius of cone = 3/2 m

Slant height of cone = 2.8 m

Surface area of tent = C.S.A of cone + C. S. A. of cylinder.
