Radius: The distance from the center to the circumference of a circle.he radius of a circle is the distance from the center point to the edge of the circle. It's the same distance anywhere on the circle, because the circle has radial symmetry. So it doesn't matter where you measure the radius on the circle, and if you know one radius measurement for a circle, then you know all of them.
Diameter:It is a crucial measurement of circles. In fact, it is one of the defining measurements of circles. The diameter measures how big the circle is from rim to rim passing through the center. Look at the following diagram to see how this measurement is taken.
Perimeter: From Latin, meaning “around” (peri)and “measure” (metron), a perimeter is basically a boundary of any kind, measuring around the shape. In mathematics, perimeter refers to the length of this boundary. In geometry class, you might be asked to calculate the perimeter of a polygon, which is the sum of the length of each side. You might also hear this word used by members of the military or a police force as in “secure the perimeter” or “the perimeter has been breached.”
Longitude:
The concept of length has its origin in the Latin word longitudo and is intended to name the physical quantity that can mark the distance between two points in space, which can be measured , according to the International System , using the meter unit
