The fircle is a
square-
like shape, but with rounded edges. It can also be described as a circle with sides. A fircle is very similar, but not the same as, a squircle.
The formula for calculating the perimeter of a fircle whose four sides have length '
L' is
P = 4L - (8-2π)r
The formula for area would be
A = LW - (4-π)r2
