Example: A circle with center at (3,4) and a radius of 6: Start with: (x−a) 2 + (y−b) 2 = r 2. Put in (a,b) and r: (x−3) 2 + (y−4) 2 = 6 2. We can then use our algebra skills to simplify and rearrange that equation, depending on what we need it for.
Write the general equation of a circle that is tangent to the x-axis, with a center located at (4,-6).
A circle graph is the graph of an equation which forms a circle. To do this we have a circle with radius r and centre (0, 0) . Using Pythagoras’ Theorem it gives the general equation: x2+y2 = r2 x 2 + y 2 = r 2. E.g. This circle has a radius of 3 so has the equation: x2+y2 = 32 x 2 + y 2 = 3 2. Which simplifies to:
Find the equation of a circle with center $O(-2,3)$ and radius $r=4$. Which of the following points belongs to the circle?
Here’s a step-by-step process to graph a circle: Step 1: Identify the center coordinates (h, k) of the circle. In the equation (x – h)^2 + (y – k)^2 = r^2, the values of h and k represent the x and y coordinates of the center of the circle. Step 2: Determine the radius, r.
3 wrz 2020 · Given the equation of a circle, we can put the equation in standard form, find the center and radius of the circle from the standard form, and then use the center and radius to graph the circle.
