The Earth is a SPHEROID. A spheroid is a slightly flattened sphere. The circumference of the Earth about the Equator is slightly longer than the circumference about the Poles. This is because of centrifugal force pushing the Earth outwards at the Equator.

NB 'Round' does not indicate a dimension.

A 2-dimensional figure is a circle.

A 3-dimensional figure is a sphere.
