The circle circumscribing the rectangle will have diameter along the diagonal of the rectangle and centre as the midpoint of the diagonal. Since the angle subtended by diameter at any point above or below it is 90 degree and here it is the interior angle of the rectange . THerefore radius = 10/2 = 5cm
