14. Determine the cost of painting the frustum part of the lamp

The top part of the table lamp is in the shape of a frustum of a cone. If the radii of circular bases are 12 \(cm\) and 4 \(cm\), and the height is 10 \(cm\), find the cost of painting the frustum part of the lamp, including the top part if \(1\) sq. cm \(= ₹0.50\).

 

 

The cost of painting the frustum part of the lamp \(=\) \(₹\)

 

[Note: Round off the cost to the whole number.]
