Actionscript:

-
var surfaceArea:Number = sphereSurfaceArea(rad);
-
var volume:Number = sphereVolume(rad)
-
trace("surface area: ", surfaceArea);
-
trace("volume:", volume);
-
trace("volume / surface area:", volume / surfaceArea);
-
-
function sphereSurfaceArea(r:Number):Number{
-
return 4 * Math.PI * r * r;
-
}
-
-
function sphereVolume(r:Number):Number{
-
return r * r * r * (4.0/3.0) * Math.PI;
-
}
-
-
/*outputs:

Last night I was feeling curious about sphere volume and sphere surface area... I used WolframAlpha to find the neccessary equations and then wrote the above code snippet...
Check out how WolframAlpha does it:
surface area of a sphere
surface area of a sphere with radius 10
sphere volume
sphere volume with radius 10

volume to surface area will always be r / 3.0
after regularly picking up ninja scrolls on a daily basis , i’m keen to see what samurai action this is leading to…
That makes sense…. thanks…. not sure exactly where I was going with this…
