A solid metal cone has radius $$\(1.65 \mathrm{~cm}\)$$ and slant height $$\(4.70 \mathrm{~cm}\)$$. A metal sphere with radius $$\(5 \mathrm{~cm}\)$$ is melted down to make cones identical to this one. Calculate the number of complete identical cones that are made. [The volume, $$\(V\)$$, of a sphere with radius $$\(r\)$$ is $$\(V=\frac{4}{3} \pi r^{3}\)$$.]
