Question 832032
Since the pendulum is 8 ft, the diameter of the circle is 16 ft.
{{{C = (pi)d}}}
{{{C = (pi)16}}}
To get the circumference in inches.
{{{C = (pi)16*12}}}
C = 603.2
9/C gives us the fraction of the circle represented by 9 inches.
percent = 9/603.2 = 0.01492
percent * 360 degrees is what we want.
0.01492 * 360 = 5.371 degrees
