Im not sure how to find the limits of this
Set up an integral to find the volume of the solid below the graph of f(x,y) = 49 - x2 - y2 and above the plane z = 9.
i think the equation becomes x^2+y^2=40 and the x limits are -sqrt(40) to sqrt(40) but im not sure. could someone please explain to me how i get the limits.
The reason why its 4 instead of 2 is because I cut both x and y intervals in half, so I needed to multiply by 2*2=4.
