Answer 2

Answer:

Rs. 1351.68

Step-by-step explanation:

Radius of each pillar = 28 cm

Height of each pillar = 4 m

Curved surface area of a cylinder = 2$\pi$rh

= 2 x 22/7 x 0.28 x 4

=49.28/7

= 7.04 m^2

Area of 24 pillars = 7.04(24) = 168.96 cm^2

Cost of painting per m^2 = Rs. 8

Total cost = Rs. 8 x 168.96 = Rs. 1351.68 = 1352(approx).
