Consider the cone 31 given by z = V505 + y2 where (3:, y) E D the disk of radius 2, with upwards orientation. We close it with its \"lid\" 32, the horizontal disk of radius 2 at level 2, with upwards orientation. We also consider the vector eld ($3913)=($:y:1)' 1. Compute the ux through the cone Mira. 2. Compute the ux through the lid [Ma 3. Deduce the flux through the surface 3 consisting of the cone with its lid, with outwards orientation. Careful of signs! 4. Recover the result of Question 3 using the divergence theorem
