1. ## [SOLVED] volume

need the volume of a sphere that is 11'8" and how you figured it - thanks!

2. 11 feet and 8 inches. Is that the radius, diameter, circumference, please be more specific.

3. The equation for the volume of a sphere is as follows:

$V = \frac {4}{3}\pi r^3$

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:

$V = \frac {4}{3}\pi (175)^3$

Now just plug it into your calculator.
