WebMar 27, 2024 · Finding the Equation of a Circle. Step 1: On a piece of graph paper, draw an x−y plane. Using a compass, draw a circle, centered at the origin that has a radius of 5. Find the point (3,4) on the circle and draw a right triangle with the radius as the hypotenuse. Step 2: Using the length of each side of the right triangle, show that the ... WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have the center at (2,3) and have a radius of 2 since 4 = 2^2. This means if you went a distance of 2 away from that center point you would be on the circle. WebJan 11, 2024 · To get a curve to graph as a circle, you need to change both the x exponent and the y exponent. As soon as you take the square of both x and y values, you get a circle coming back unto itself! Often the … how to see pop ups in edge
