Find the length of a radius of a circle such that the circumference of the circle is numerically equal to the area of the circle.
\n" ); document.write( "-----------------------
\n" ); document.write( "C = (pi)(2r)
\n" ); document.write( "A = (pi)r^2
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "(pi)(2r) = r^2
\n" ); document.write( "-------
\n" ); document.write( "2r = r^2
\n" ); document.write( "---
\n" ); document.write( "r^2-2r = 0
\n" ); document.write( "r(r-2) = 0
\n" ); document.write( "Positive solution:
\n" ); document.write( "radius = 2
