WebSep 21, 2024 · The diameter of a circle is twice the length of the radius, so the equation can also be written as: Area = π * (d/2)^2. Thus, the diameter is directly proportional to the area. As the diameter increases, the area of the circle will also increase. Another relationship that can be explored is the circumference of a circle. WebThis diameter is twice that of the radius of a circle i.e. D=2r, where ‘D’ is the diameter and ‘r’ is the radius. Radius of a circle = Diameter/2 Or. Diameter of a circle = 2 x Radius. Equation. The equation of a circle includes the radius and it is given by: (x-h) 2 + (y-k) 2 = r 2. Where (h,k) is the center of circle. Radius of circle ...
