need the volume of a sphere that is 11'8" and how you figured it - thanks!
The equation for the volume of a sphere is as follows:
$\displaystyle V = \frac {4}{3}\pi r^3$
If your sphere has a diameter of 11'8", or 350cm in metric, then it has a radius of 175cm.
Plug this into the equation:
$\displaystyle V = \frac {4}{3}\pi (175)^3$
Now just plug it into your calculator.
