9x + 26 + 7x - 17 = 2x + (-3x) + 5x =
16x + 9 = 2x - 3x + 5x =
16x + 9 = 4x
9 = 4x - 16x
9 = - 12x
-9/12 = x

The question "how much space is inside a solid?" is actually asking about the volume of that solid.

The volume of a cone is given by

$V = \dfrac{1}{3}\pi hr^2$

where h is the height of the cone, and r is its radius.

So, you only need to plug in the values:

$V = \dfrac{1}{3}\pi\cdot 50 \cdot 200^2 = \dfrac{2000000\pi}{3}m^3$
