Step-by-step explanation:
Curved Surface Area of Cylinder =
R = 0.28 m
H = 35 m
So,
= 2πrh
= 2 × 22/7 × 0.28 × 35
= 2 × 22/7 × 28/100 × 35
= 2 × 22 × 4 / 100 ×35
= 44 × 4/20 × 7
= 44/× 1/5 × 7
= 61.6 m^2
16 pillars CSA = 61.6 ×16
= 985.6 m^2
Rate = 5.50 / m^2
= 985.6 × 5.50
= ₹ 5420.8. Answer.
I hope it is correct!!!
