The diameter = 1.4 m
Radius = 1/2 of diameter. = 1.4 / 2 = 0.7 m
Length of the garden = 2m
Surface area of the circle =  2 x pie x r x l
                                     = 2 x 22/7 x 0.7 x 2 = 8.8 m²
Revolution = 5
Si total area = 5 x 8.8 = 44 m²

Diameter = 1.4 m
r = d/2
r = 1.4/2
r = 0.7m
curved  surface area of cyclinder = 2 * 22/7 * r^2                                                                                                     = 2 * 22/7 * 0.7 * 0.7                                                  = 8.8 m^2
                           No of revolution = 5
Therefore  = 8.8 * 5                    = 44 m2
