23 maj 2021 · The distance around a circle is its circumference. The distance from the center to the circle is its radius. The longest distance between two points on a circle is the diameter, which is a line segment running through the center. A circle is the shape with the shortest perimeter enclosing an area.
Radius, Diameter and Circumference. The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. And here is the really cool thing:

Radius Formula from Circumference. Circumference is the total distance of the boundary of the circle given by 2r. Circumference = C = 2 π r. r = C 2 π. Radius Formula from Area. The space or region enclosed within the circumference of the circle is its area. Area of a circle = π r 2. Radius = A r e a π.
