WebbWe can use the algebraic identity formula of (a - b) 2 = a 2 + b 2 - 2ab to convert the standard form of equation of circle into the general form. Let's see how to do this conversion. For this, expand the standard form of the equation of the circle as shown below, using the algebraic identities for squares: \( (x - x_1)^2 + (y - y_1)^2 = r^2\) WebbThe standard form of circle equation is, (x − a) 2 + (y − b) 2 = r 2 So, (x − 4) 2 + (y − 5) 2 = 7 2 So, (x − 4) 2 + (y − 5) 2 = 49 Question 2: Find the centre and radius of the circle whose equation is given by x2 + y2 – 10x + 14y + 38 = 0. Solution: Given circle equation is: x 2 + y 2 – 10x + 14y + 38 = 0 x 2 -2 (5)x + y 2 + 2 (7)y + 38 = 0

Convert Circle Equations from Expanded Form to Standard form 2

WebbThis calculator will find either the equation of the circle from the given parameters or the center, radius, diameter, circumference (perimeter), area. Equation of a Circle Calculator … WebbThe Standard form of a circle is (x−h)2 +(y− k)2 = r2 ( x − h) 2 + ( y − k) 2 = r 2, where r r is the radius and (h,k) ( h, k) is the center. By knowing the center and radius of the circle we … WebbUse the distance formula to find the length of the diameter, and then divide by 2 to get the radius. Then find the midpoint of the diameter which will be the center of the circle. Now you have the coordinates of the center and the radius and that is all that is necessary to write the standard equation of the circle. eyefinity vision provider
