Answer:Hey mate hope it will help you

Explanation:given diameter of cylinder=15ms

                     ∴ radius=15ms/2=7.5ms

                height=2.4ms

                        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

                                          ∴l=√h*h+r*r

                        l=√4*4+7.5*7.5

                      l=13.275

                         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
