If the radius of the base of a right circular cylinder is 4 m and the area of the curved surface of the cylinder is 19.5 m2, then its volume (in m3 ) is:
Simplify \(\frac{\left[ \tfrac{3}{5}\,\text{of}\,\left(15\tfrac{2}{3} - 33\tfrac{1}{3}\right) + \tfrac{1}{3}\left(18\tfrac{3}{4}\,\text{of}\,7\tfrac{1}{5} \div 15 \times 2\right) \right] \times 5}{3^2 \times 5 + 1}\):
