Question

in a building there are 40 cylinder pillars. the radius of each pillar is 56cm and height is 8m. find the total cost of painting the surface of all the pillar at the rate of rs.10/ square meter.

Answer 1

r=56cm

h=800cm

area of 40 cylinder =2πrh * 40

=(22/7)*56*800*40

=22*8*800*40

=5632000cm²

now change in meter and multiply by 10

=(5632000/100*100)*10

=5632rupees.

can you give me brainly.
