Circumference of the base of a cylinder, open at the top, is \( 132 \mathrm{~cm} \). The sum of radius and height is \( 41 \mathrm{~cm} \). Find the cost of polishing the outer surface area of cylinder at the rate \( ₹ 10 \) per sq dm (decimetre). \( \left(\right. \) use \( \left.\pi=\frac{22}{7}\right) \)
