WebThe equation of a circle is x2+y2 =r2 x2 + y2 = r2, where r represents the radius (with a centre at 0,0 0,0 ). The definition of a circle is a set of all points on a plane that are a fixed … The formula for a circle is (x−a)2 + (y−b)2 = r2 So the center is at (4,2) And r2 is 25, so the radius is √25 = 5 So we can plot: The Center: (4,2) Up: (4,2+5) = (4,7) Down: (4,2−5) = (4,−3) Left: (4−5,2) = (−1,2) Right: (4+5,2) = (9,2) Now, just sketch in the circle the best we can! How to Plot a Circle on the Computer See more Let us put a circle of radius 5 on a graph: Now let's work out exactlywhere all the points are. We make a right-angled triangle: And then use … See more Now let us put the center at (a,b) So the circle is all the points (x,y) that are "r" away from the center (a,b). Now lets work out where the points are … See more Now imagine we have an equation in General Form: x2 + y2+ Ax + By + C = 0 How can we get it into Standard Formlike this? (x−a)2 + (y−b)2 = … See more But you may see a circle equation and not know it! Because it may not be in the neat "Standard Form" above. As an example, let us put some values to a, b and r and then expand it And we end … See more WebAnswer: (2, – 3) Step 4: Here is the graph of the line intersecting the circle at (– 3, 2) and (2, – 3). Example 4: Solve the system of nonlinear equations. Substitute the expression of y y from the top equation to the y y of the bottom equation.
