The area of a circle is a mean proportional
between any two regular and similar polygons of which one
circumscribes it and the other is isoperimetric with it.
In addition, the area of the circle is less than that of any
circumscribed polygon and greater than that of any
isoperimetric polygon. And further, of these
circumscribed polygons, the one that has the greater number of sides
has a smaller area than the one that has a lesser number;
but, on the other hand, the isoperimetric polygon that
has the greater number of sides is the larger.

It's possible to control the length of lines in a much more
general way, if simple changes to \verb|\leftskip| and
\verb|\rightskip| aren't flexible enough for your purposes. For
example, a semicircular {hole} has been cut out of the present
paragraph, in order to make room for a circular illustration that
contains some of {Galileo}'s immortal words about {circle}s; all
of the line breaks in this paragraph and in the circular quotation
were found by \TeX's line-breaking algorithm. You can specify an
essentially arbitrary paragraph shape by saying
\verb|\parshape=<number>|, where the \verb|<number>| is a positive
integer $n$, followed by $2n$ \verb|<dimen>| specifications. In
general, `\verb|\parshape=|$n$ $i_1$~$l_1$ $i_2$~$l_2$ $\ldots$
$i_n$~$l_n$' specifies a paragraph whose first $n$ lines will have
lengths $l_1$, $l_2$, \dots,~$l_n$, respectively, and they will be
indented from the left margin by the respective amounts $i_1$,
$i_2$, \dots,~$i_n$. If the paragraph has fewer than $n$ lines,
the additional specifications will be ignored; if it has more than
$n$ lines, the specifications for line $n$ will be repeated ad
infinitum. You can cancel the effect of a previously specified
\verb|\parshape| by saying `\verb|\parshape=0|'.
