A sphere is indeed a three dimensional shape. It is a circle rotated about an axis several times to create and three dimmensional object from a two dimensional shape.
Because a sphere is a 3 dimensional shape.
The shape of the globe is a sphere.

A sphere is a three dimentional shape, a circle is a two dimentional shape. You can't pick up a circle, it can only be drawn. In differential geometry, a one dimensional sphere is a point, a two dimensional sphere is a circle and a three dimensional sphere is what we call a "sphere", there is no limit to the number of dimensions a sphere can have.
None normally because a pentagon is 2 dimensional 5 sided shape whereas a sphere is a 3 dimensional globular shape.
