👉 The term "peripherial" refers to a part or region of an object that is located closer to its center than other parts. In the context of geometry, it can be used in describing the shape of a circle, where the central point (the center) is at the circumference and the periphery is the boundary around the circle.
For example, consider a circle with a radius of 5 units. The perimeter of this circle would be calculated as:
Perimeter = 2
