Let c be the unit circle in the xy-plane, oriented counterclockwise as seen from above. the divergence of the vector field f~ = (z, x, y) is zero, and as a result the flux through every surface with boundary c should be the same. confirm that this is the case with the upper half of the unit sphere, the lower half of the unit sphere, and the unit disk in the xy-plane

Upper half of the unit sphere (call it ): parameterize by

with and . Take the normal vector to be

Then the flux of over this surface is

Lower half of the sphere (call it ): all the details remain the same as above, but with . The flux is again .

Unit disk (call it ): parameterize the disk by

with and . Take the normal vector to be

Then the flux across is

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
