Question

plz answer the question​

Answer 1

Answer:

r= 60 cm

h= 84 cm

c.s.a of cylinder = 2 x pie x r x h

                          = 2 x 22/7 x 60 x 84

                          = 31,680 cm^2

total no. of revolution= 500

therefore area pressed = 500 x 31,680

                                       = 1,58,40,000 cm^2

cm to m = 1,58,40,000 / 1000000

              = 15.84 m^2

HOPE U R SATISFIED WITH MY ANSWER!!!!!!!
