Answer 2

Step-by-step explanation:

We must find the curved surface area of each pillar

(the top and bottom would be attached to the ceiling and floor)

CSA of cylinder is 24 × 7 × 2 × 22/7

$2\pi \: r \: h$

SO THE CSA OF THE PILLAR IS

24 × 7 × 2 × 22/7 => 1056

$cm {}^{2}$

Since it is 15 pillars

15 × 1056 = 15840 cm squared is the CSA of all the 15 pillars

15840 cm^2 is equal to 1.5840 m^2

Cost is 2 × 1.5840 = 3.168 RUPEES
