Circle (Radius, Diameter, Circumference)
Radius is the distance from the center to the edge.Diameter starts at one side of the circle, goes through the center and ends on the other side.Circumference is the distance around the edge of the circle.
A circle is a two-dimensional shape consisting of all points equidistant from a given point known as the center of the circle. Some important terms related to a circle are:
1. Radius: The distance from the center of a circle to any point on the circumference of the circle is known as the radius of the circle. It is denoted by ‘r’.
2. Diameter: The diameter of a circle is twice the length of the radius. It is the distance across the circle, passing through the center of the circle. It is denoted by ‘d’.
3. Circumference: The circumference of a circle is the total distance around the circle. It can be calculated using the formula given below:
Circumference = 2πr or Circumference = πd
where π (pi) is a mathematical constant and is approximately equal to 3.14.
In summary, the radius is the distance from the center of the circle to its circumference, the diameter is the distance across the circle passing through its center and the circumference is the total distance around the circle.
