21. Find the volume of paint required

The pillars of a castle are shaped like a cone surmounted on a cylinder of height 27 \(m\). The radius of the pillar is 28 \(m\) and the slant height is 8.6 \(m\). If there are 13 congruent pillars in the castle and each litre of paint can cover 12 \(m^2\), then find the total volume of paint required. [Hint: Use \(\pi = \frac{22}{7}\).]

 

 

Answer:

 

The total volume of paint required is  litres.

 

[Note: Enter the answer rounded to the whole number.]
