#V=103.5pi# or #324.99#

Explanation:

The equation for the volume of a cylinder is #V=pir^2h#
If the diameter of the cylinder is 6, then the radius is half of that, or 3. So plug your numbers into the equation and solve:
#V=pi3^2(11.5)#

3 squared is 9, and #9*11.5=103.5#

So the volume of the cylinder is #103.5pi# , or 324.99
