find center, circumference, and area of a circle with endpoints: (2,-1) and (-14,-5)
\n" ); document.write( "***
\n" ); document.write( "midpoint of given coordinates=coordinates of the center
\n" ); document.write( "(x1+x2)/2, (y1+y2)/2
\n" ); document.write( "=(-14+2)/2, (-5-1)/2
\n" ); document.write( "=(-12/2), (-6/2)
\n" ); document.write( "center:(-6,-3)
\n" ); document.write( "..
\n" ); document.write( "radius of circle=distance from center to one of end points(2,-1)
\n" ); document.write( "distance=√(x1-x2)^2+(y1-y2)^2)=√(2+6)^2+(-1+3)^2)=√(64+4)=√68
\n" ); document.write( "circumference=2π*radius=2π√68≈51.81
\n" ); document.write( "Area=π*radius square=π*(√68)^2=68π≈213.63 \n" ); document.write( "
\n" );
