Answer 1

Answer:

Given ,

length = height = 150 cm

                          = 1.5 m

diameter = 70 cm

radius = 35 cm

           = 0.35 m

CSA of roller = 2×22/7 × 0.35 × 1.5

                      = 0.75 × 44

                      = 33 m²

No of revolutions made = 750

Area covered = 750 × 33

                       = 24750

cost per m² = 75 p

cost = 24750× 75

       = 1856250 p

       = Rs . 18562 . 50
