Diameter is twice the length of the radius, or the equation {eq}Diameter = 2radius {/eq}. Below is a diagram showing the radius and diameter of a circle, they are abbreviated as r and d. The radius and diameter are shown in this circle. The radius can be used to compare circle ...
Radius of a circle is the distance between center of circle and the point on circle. Radius is half of diameter, the longest chord of circle. Circumference is the distance around the circle. Radius formula and equation at BYJU’S.
In geometry, conic sections are curves generated as the intersection of the surface of a cone with a plane. The three types of conic sections are: ellipse/circle, parabola, and hyperbola. Each has different components and forms. In a circle, the general form of the equatio...
