Answer:
Step-by-step explanation:
Radius of the pillar = 28cm
Height of the pillar = 4cm
cost of painting = Rs 8 per square meter
CSA of cylinder = 2πrh
= 2× 22/7 × 28 × 4
= 704 cm²
CSA of 12 pillars = 12 × CSA
= 12 × 704
= 8448 cm²
Total cost of painting = 8 × CSA of 12 pillars
= 8 × 8448
= RS 67584
