Answer:

220,63 m²

Step-by-step explanation:

cylinder                               cone

H  = 4.8m                        r  =  4.5m             l ² =  4 .5² +  6²

R = 4.5m                        h   =  10.8 - 4.8          =  20.25 +36    = 56.25

                                          = 6 m                 ∴   l = √56.25  =  7.5m            

 Canvas required for tent   =  CSA of a cylinder  + CSA  of cone

                                             =  2πRH   + π rl

                                            = 2 x 22/7  x 4.5 x 4.8     + 22/7 x 4.5 x 6

                                           = 135 .77 + 84.86

                                          = 220.63 m²
