Who can remember that formula ::slices on a weird pizza pie
if each angle is 162 then to bisect that and extending it to the center of the polygon gives us 81 degrees
so 162 -180 gives us the angle at the center for each slice of the pie or 18degrees.
now divide 360 by 18 gives you 20

20 x 7 inches (crust length for each slice) = 140 answer d
