You can solve for volume using radius or diameter.
Sphere Volume   = <span>  4/3 • <span>π <span>• r³ <span>    =     <span>( <span>π <span>•d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
</span></span></span></span></span></span></span>
<span>Volume = 3.14159 * 3.0^3 / 6
</span>
<span>Volume = 3.14159 * 9 / 2

</span><span><span><span><span>Volume = </span>14.137 cubic centimeters
 </span></span></span>

So if 3/4 of the seats are filled, there are a few methods we can use.

The simplest method:

Just multiply 3/4 by 500, to get 1500/4, or 375.

So 375 seats are filled.

A method that can be used with harder problems and will be more efficient in those cases:

Using proportions.

You could say,

?/500 = 3/4

And then cross multiply,

500 * 3 = 4 * x (say the ? = x)

1500 = 4x

/4         /4

x = 375

So either way we get the answer, 375 seats were filled.
