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.
a shape with equal sides
error in shape,size,or distance
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.

That shape is called a circle.
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.
If the shape is two-dimensional then it is a circle, if the shape is three-dimensional then it's a sphere.
It is a pair of compasses.

A sphere.
A circle is the set of all the points that have the same distance from a given point (its center). If you rotate a shape, you rotate it in such a way that you keep any point a fixed distance from the center of rotation.
