A sphere if you revolve

If you must do this with integration, you can just move it over the the origin.

Now, revolve a circle of radius 1/2.

or leave it where it is and:

Physicists and mathematicians use the opposite definition right.

If you use the physicists' you get a sphere.

If you the mathematicians' you get this weird figure I've showed above.
