We go from 10x+20 = 50 to 10x = 30 after we subtract 20 from both sides. So we use the subtraction property (of equality).

Answer: 1962.4 cubic mm

Step-by-step explanation:

The volume of the larger cone is $V=\frac{1}{3}(\pi)(10^{2})(20)=\frac{2000\pi}{3}$

The volume of the smaller cone is $V=\frac{1}{3}(\pi)(3^{2})(14)=42\pi$ .

So, the volume is $\frac{2000\pi}{3}-42\pi \approx \boxed{1962.4}$
