A canvas tent is in the form of a cylinder of diameter 15m and height 2.4m surmounted by a cone of equal base and height 4m. Find the cost of canvas

required at 50/sqm.


Given diameter of cylinder=15ms
                     ∴ radius=15ms/2=7.5ms
                        surface area of cylinder =2πrh
                                                                 =2*22/7*7.5*2.4 m*m
                                                                   =113.14m *m
                                  since it is given equal base radius is also equal
                             ∴radius of cone =7.5ms
                                 given height =4m
                         c.s.a. of cone =π*r*l
                                                 =22/7 *7.5*13.2 =312.91m*m
                                         total surface area = c.s.a of cylinder +c.s.a of cone
                                                                   =113.14+312.91 =426.05m*m
                             cost of canvas per m square =50RS
                                             ∴cost of canvas required=426.05*50 =21302.5 RS
