(x - h)^2 + (y - k)^2 = r^2
\n" ); document.write( "where (h,k) is the vertex, and (r) is the radius
\n" ); document.write( "r^2 = 25
\n" ); document.write( "r = 5
\n" ); document.write( "This is a circle with a radius of five units.
\n" ); document.write( "Area = (pi)r^2
\n" ); document.write( "Area = 25(pi) \n" ); document.write( "
