Frequently Asked Questions
What is the standard formula for a circle?
The standard equation of a circle is given by: (x-h) 2 + (y-k) 2 = r 2. Where (h,k) is the coordinates of center of the circle and r is the radius. Before deriving the equation of a circle, let us focus on what is a circle? A circle is a set of all points which are equally spaced from a fixed point in a plane.
How to write the equation of circle?
Writing the Equation of a Circle Given the Endpoints of a Diameter. Step 1: Find the center of the circle, {eq}(h,k) {/eq}, by finding the midpoint of the diameter. Step 2: Find the radius, {eq}r ...
What is the equation of a circle?
The circle equation general form is expressed as: {eq}x^2 + y^2 + Ax + By - C = 0 {/eq} Where, considering P (x, y) as a point in the circumference of a circle, some terms of the equation are:
What is the formula for the graph of a circle?
The equation of a circle is (x - h) 2 + (y - k) 2 = r 2 where r is equal to the radius, and the coordinates (x,y) are equal to the circle center. The variables h and k represent horizontal or vertical shifts in the circle graph.
