WebMar 12, 2024 · The radius of a circle is the distance along a line drawn from its center to one of its ends, whereas its diameter is equal to double that distance. Using this concept, the diameter formula is. d = r × 2. Where, d = diameter. r = radius. WebGo through the following problems to find the diameter of a circle. Example 1: Find the diameter of a circle if its radius is 3 cm. Solution: Given: Radius, R= 3 cm. We know that, if the radius is given, the formula to calculate the diameter is: D = 2R. Substitute R = 3 cm in the formula, we get. D = 2(3) D = 6 cm.
