In a temple there are 25 cylindrical pillars. The radius of each pillar is 28cm and height 4m. Find the total cost of painting the curved surface area of pillars at the rate of Rs. `8 per m^2`

Explanation

To solve the problem step by step, we need to find the total cost of painting the curved surface area of 25 cylindrical pillars. Here’s how we can do it:

### Step 1: Find the curved surface area of one pillar.
The formula for the curved surface area (CSA) of a right circular cylinder is given by:

\[ \text{CSA} = 2 \pi r h \]
