Find radius of a circle from diameter

WebWhen the diameter of a circle is known, the formula is, Radius = Diameter/ 2. For example, if the diameter is given as 24 units, then the radius is 24/2 = 12 units. When the circumference of a circle is known, the formula is, Radius = Circumference/2π. If the circumference of a circle is given as 44 units, then its radius can be calculated as ... WebFeb 17, 2016 · A. In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units. C = 2 π r = 2 π × 5 = 10 π units. Q.
