I need to find radius of circle with given information - shaded area of circle is 40 degrees and area of that shaded area is 59in^2.
\n" ); document.write( "------
\n" ); document.write( "# of such sectors in the circle = 360/40 = 9
\n" ); document.write( "----
\n" ); document.write( "9*59 = 531 sq in (total area of the circle)
\n" ); document.write( "--------------------------
\n" ); document.write( "Solve for \"r\":
\n" ); document.write( "(pi)r^2 = 531 sq.in
\n" ); document.write( "r^2 is very close to 169.0225
\n" ); document.write( "r = 13 inches
\n" ); document.write( "====================
