Since the pendulum is 8 ft, the diameter of the circle is 16 ft.
\n" ); document.write( " $\"C+=+%28pi%29d\"$
\n" ); document.write( " $\"C+=+%28pi%2916\"$
\n" ); document.write( "To get the circumference in inches.
\n" ); document.write( " $\"C+=+%28pi%2916%2A12\"$
\n" ); document.write( "C = 603.2
\n" ); document.write( "9/C gives us the fraction of the circle represented by 9 inches.
\n" ); document.write( "percent = 9/603.2 = 0.01492
\n" ); document.write( "percent * 360 degrees is what we want.
\n" ); document.write( "0.01492 * 360 = 5.371 degrees
\n" ); document.write( " \n" ); document.write( "
