Find the equation of a circle using the centre and radius

WebThe circumference of a circle and radius are related to each other and their relation can be expressed as Circumference = 2πr, where 'r' is the radius. So, when the circumference is known, the formula used to calculate the radius of a circle is Radius = Circumference / 2π. What is the Radius Formula? WebOct 23, 2011 · The equation for the circumference of a circle can be written in two ways: C = 2πr. C = πd. Where: r represents the radius of the circle, and d represents a circle's diameter. Recall that the radius is the distance from the center of the circle to a point on the edge of a circle, and the diameter is the largest distance across a circle. suzuki dtc b1141
