The arc function can also calculate the outside (default) and inside
lengths of arched walls. The outside arched wall lengths are meas-
ured outside of the arc (see diagram below). The inside arched wall
lengths are measured inside of the arc (see diagram on page 43).

Find the radius of an arched window with a chord length of 8 Feet 1
Inch and a rise of 2 Feet and 10-1/2 Inches. Then, find the arc
angle, arc length and segment area of the window. Then find the
“outside” arched segment wall lengths in order to frame the window.
