Answer:

132m²

Step-by-step explanation:

diameter(D)= 1.4m

radius(r)=d/2

            =0.7m

height=2m

Area covered in 1 revolution= Lateral surface area

                                             =2πrh

                                             =2×22/7×0.7×2

                                              =2×22× 7 ×2

                                                     7   10

                                              =4×2.2

                                               =8.8m²

area covered in 15 revolutions = 15×8.8 m²

                                                  =132.0m²
