Answer 2

HEY MATE ,

HERE IS YOUR ANSWER

Diameter=50cm

Radius=25cm

Height=3.5m=350cm

$curved \: surface \: area = 2\pi \: rh \\ = 2 \times \frac{22}{7} \times 25 \times 350 \\ = 2 \times 22 \times 25 \times 50 = {55000cm}^{2}$

$\frac{55000}{100} = {55m}^{2} \\ cost \: of \: painting \: {1m}^{2} = 10 \\ cost \: of \: painting \: {55m}^{2} = 10 \times 55 \\ = 550$

Therefore Cost Of Painting The Pillar Is ₹550.
