WebJun 15, 2024 · Example 6.21. 3. Graph x 2 + y 2 = 9. Solution. The center is ( 0, 0). Its radius is the square root of 9, or 3. Plot the center, plot the points that are 3 units to the right, left, up, and down from the center and then connect these four points to form a circle. Figure 6.21. 3. Example \PageIndex {4 \PageIndex {4. WebStandard Equation of a Circle. The left graph shows the equation and graph of the circle with center at (0,0) while the right graph shows the equation and graph of the circle with center at (h,k). For a circle with a form Ax 2 + Ay 2 + Dx + Ey + F = 0, the center (h,k) and radius (r) can be obtained using the following formulas.
WebThe equation of the circle requires the radius NOT the diameter. Remember the radius is half the diameter. The radius is always a positive number Since the radius is a length it is always positive. E.g. The radius of this circle is 1212 and r 2 = 144r2 = 144. The equation of this circle is x 2 + y 2 = 144x2 + y2 = 144 WebAug 23, 2024 · Graph a Circle. Any equation of the form \((x-h)^{2}+(y-k)^{2}=r^{2}\) is the standard form of the equation of a circle with center, \((h,k)\), and radius, \(r\). We can then graph the circle on a rectangular coordinate system. Note that the standard form calls for subtraction from \(x\) and \(y\).
