Graphing circle equation
WebThe graph of a circle is completely determined by its center and radius. Standard form for the equation of a circle is (x − h) 2 + (y − k) 2 = r 2. The center is (h, k) and the radius measures r units. To graph a circle mark … WebThis means that, using Pythagoras’ theorem, the equation of a circle with radius \(r\) and centre (0, 0) is given by the formula \(x^2+ y^2= r^2\). Example Find the equation of a circle with ...
