Question

A tent is cylindrical in shape with a conical top above it. The radius of the base of the tent is 7 m. The height of the cylindrical part is 20 m and the height of the conical part is 4 m. Find the area of canvas cloth needed to construct the tent.

Answer 1

Answer:

Volume of cylindrical part = π r2h

                                     = × 7 × 7 × 20 m3  

                                      = 3080 m3

Step-by-step explanation:

Volume of cylindrical part = π r2h

                                     = × 7 × 7 × 20 m3  

                                      = 3080 m3

Volume of conical part =π r2h

                              = x x 7 x 7 x 4m3

                                = 205.3 m3

...Volume of air in tent = volume of cylindrical part + volume of conical part  

                               = (3080 + 205.3) m3  

                               = 3285.3 m3
