The pillars of a castle are shaped like a cone surmounted on a cylinder of height 23 \(m\). The radius of the pillar is 42 \(m\) and the slant height is 8.2 \(m\). If there are 12 congruent pillars in the castle and each litre of paint can cover 17 \(m^2\), then find the total volume of paint required. [Hint: Use \(\pi = \frac{22}{7}\).]
Total surface area of the pillar is __________ \(m^2\).
Total area to be painted \(=\) ___________ \(m^2\).
Volume of paint required \(=\) __________ litres
