Let The circumference = $\"C\"$
\n" ); document.write( "Let the radius = $\"r\"$
\n" ); document.write( " $\"C+=+2%2Api%2Ar\"$
\n" ); document.write( " $\"C+=+25%2Api\"$
\n" ); document.write( "----------
\n" ); document.write( "given:
\n" ); document.write( " $\"200%2F5\"$ rotations/min
\n" ); document.write( " $\"%28200%2F5%29+%2A%28+60%2F1%29\"$ rotations/min x min/hr
\n" ); document.write( " $\"2400\"$ rotations/hr
\n" ); document.write( " $\"2400\"$ rotations/hr x $\"25%2Api\"$ in/rotations = $\"188495.56\"$ in/hr
\n" ); document.write( " $\"188495.56\"$ in/hr x $\".5\"$ hr = $\"94247.78\"$ in in 1/2 hr
