Imagine the path of the tip of the pendulum as an arc of a circle. The circle would have a radius of 4 feet and the arc would be 20 degrees. To calculate the length of the arc, you need to find 20 degrees of the circumference.
Length of Arc = 2*pi*R*Degree of arc/360
Length of Arc = 2*pi*4*20/360
Length of Arc = 8pi * 1/18
Length of Arc = 4/9 pi feet
<span>Length of Arc ~ 1.396263402 feet
