Answer:
The radius of a circle is the distance from the center of the circle to any point on its circumference. It is usually denoted by 'R' or 'r'.
A radius is a line segment with one endpoint at the circle's center and the other endpoint in the process. Radius = Diameter of a Circle: A line segment passing through the center of a circle, and having its endpoints on the ring, is called the circle's diameter. Diameter = 2 × radius.
Example: If the diameter is given as 24 units, then the radius is 24/2 = 12 units. If the circumference of a circle is provided as 44 units, then its radius can be calculated as 44/2π. This implies, (44×7)/(2×22) = 7 units.
We can look at a pizza pie to find real-world examples of diameter and radius. Look at the pizza to the right which has been sliced into 8 equal parts through its center. A radius is formed by making a straight cut from the center to a point on the circle.
