WebAug 2, 2024 · 1. If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. [1] Example. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. 2. If you know the circumference of the circle, divide it by π to get the diameter. WebSurface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.Visual on the figure below: A sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). π is, of course, the well-known …
