a circle
a shape with equal sides
The distance around a two dimensional shape is known as the perimeter of the shape. If the shape is circular, it may be refered to as a circumference.

Circumference. If you have a rectangle, then the circumference (length of the sides) is equal to 2*height + 2*width.
A cube is a 3D shape that has 6 faces of equal area.

Equilateral
That shape is called a circle.
The shape you are describing is a circle. A circle is defined as the set of all points in a plane that are equidistant from a central point, known as the center. The curved side of a circle is its circumference, which is always the same distance (the radius) from the center.
Gravity exhibits equal force on all parts, so the distance from the center is about the same on all parts of earth.
A circle or a sphere
A circle has a round shape in which every point on the circle is the same distance from one point called "the center". The center of a circle is not on the circle.
It is a pair of compasses.
If the shape is two-dimensional then it is a circle, if the shape is three-dimensional then it's a sphere.
