Answer 2

Answer: ₹ 998

Step-by-step explanation:

No. of cylindrical pillars = 15

Diameter of each pillar = 18cm

Height of each pillar = 4.9m = 490cm

CSA pf pillar = $2\pi rh$

= $2*22/7*18/2*490$

= $22*18*70$

= $27720$

$1m^2 = 1/10000cm^2$

so...

$27720/10000 = 2.772m^2$

Cost of painting = $20/m^2$

$2.772*18*20$

= [tex]997.92\\ [/tex]

Which when rounded of, becomes ₹998
