finding the exact sniffed s volume limited by the plane x + y + z = 1 and z =4 - x^2- y^2

a) Make the stroke of the two supercies on one screen and, inspection , indicating that shape is the intersection curve . b ) Find the equations describing curves border region of integration. For this, solve the system of equations with unknowns x, y, arising from supercies given . c ) Trace, in two dimensions, the region of intersection and take it as a basis for l identied the limits of integration. d ) Ask and evaluate the double integral.
