# Math Help - volumes

1. ## volumes

if a spherical gas tank has an inside radius of 6'6" and is half full how many cubic feet of gas does it contain

2. Use $V = \frac{4\pi r^3}{3}$ then divide the volume by 2.

Did you copy this question completely and acurately as you have got it?

If so then this question could be a trick question: If the pressure in the gas tank is only slightly greater than the athmospherical pressure, surrounding the tank, then the tank would be filled with gas completely.

The wording of the question only makes sense if the content is a liquid.
