$\"r=%280.75V%2Fpi%29%5E%281%2F3%29\"$ and $\"V+=+32%2Api%2F3\"$
\n" ); document.write( "All we have to do is use the second equation, which tells us what V is, and substitute for V in the first equation:
\n" ); document.write( " $\"r=%280.75%2832%2Api%2F3%29%2Fpi%29%5E%281%2F3%29\"$
\n" ); document.write( "The $\"pi\"$ 's cancel and 3 divides into 0.75 0.25 times. This gives us:
\n" ); document.write( " $\"r=%280.25%2A32%29%5E%281%2F3%29\"$
\n" ); document.write( "Since 0.25*32 is 8:
\n" ); document.write( " $\"r=%288%29%5E%281%2F3%29\"$
\n" ); document.write( "Since 1/3 as an exponent means cube root and since $\"2%5E3+=+8\"$ :
\n" ); document.write( "r = 2\r
