title: Wolfram alpha, double integral over a plot or region
body: <p>Im trying to do some homework in which they gave me a domain and a double integral.</p>
  
  <p>I was trying to use wolfram alpha or symbolab to know how to do it but I can't get them to work, with wolfram I get to draw the domain but I dont know how to integrate with that <a href="https://www.wolframalpha.com/input/?i=plot%204%3C%3Dx%5E2%2By%5E2,x%5E2%2By%5E2%3C%3D16,y%3E%3D0" rel="nofollow noreferrer">domain</a>, because I have the integral, which is ∫∫D( x2 + 5y2 )dxdy and the D is the Domain I have in the plot, so Im trying to search some way to tell wolfram you have this plot and you need to calculate this integral in this domain, but I don't know how.</p>
