We know that,
Curved surface area of cylinder = \(2\pi rh
\)
264 = \(2\pi rh
\)
r = \(\frac{264}{2\pi h}\)
r = \(\frac{132}{\pi h}\) m
We also know that,
Volume of cylinder = \(2\pi rh
\)
= 924 m3
Now,
r = \(\frac{132}{\pi h}\)
= \(\frac{132\times7}{22\times6}\) = 7 m
Therefore,
Diameter of the pillar, d = 7 × 2 = 14 m
