Answer

Please see the graph.

Work Step by Step

$x^2+y^2 >4$ This is the equation of a circle with radius 2. If a point is a valid solution to the inequality, then it will be inside the circle. We pick the point $(4,1)$ to determine if this is part of the solution set. $x^2+y^2>4$ $4^2+ 1^2 > 4$ $16 +1 >4$ $17 > 4$ (true) This point is outside the circle, so it is part of the shaded region.
