Question

Describe the radius and diameter of a circle.

Answer 1

Answer:

While the radius of a circle runs from its center to its edge, the diameter runs from edge to edge and cuts through the center. ... Radius and diameter are close friends – a circle's radius is half the length of its diameter (or: a circle's diameter is twice the length of its radius)

Answer 2

Radius formula is simply derived by halving the diameter of the circle. When we connect a point on the circumference of a circle to the exact centre, then the line segment made is called the radius of the ring. The distance between the center of the circle to its circumference is the radius.

The diameter of a circle is a line segment that passes through the center of a circle and has two endpoints at the circumference. It is twice the length of the radius of a circle, i.e., Diameter = 2 × Radius.

Here is ur answer.
