Circle radius

Circle Radius(circles) – a segment that connects the center of a plane figure with its boundary line. The online calculator allows you to find the radius of a circle based on the initial value of the circumference length.

The size of any circle depends on one single parameter that is used when drawing it– this is the radius. The radius of a circle is defined as the distance from the center of the circle to each point on it. The radius of a circle is directly proportional to the circumference and diameter. The radius of circles inscribed and circumscribed around polygons is also related to other measurements.

The radius of a circle represents the equal distance of all points on the circumference from its center. Regardless of the size of the circle, the radius represents the ratio of the circumference to twice the numberπ, approximately equal to 3.14.

The radius can also be calculated based on the area of the circle. To do this, extract the square root of the ratio of the circle's area to the numberπ.

The simplest way to determine the radius of a circle– through the diameter. The diameter is twice the radius, so to find the radius, divide the diameter by two:
