All the points (x, y) in a plane that are equidistant from a fixed center point. But your WebAlgebra. In this case, r r is the distance between (2,7) ( 2, 7) and (3,8) ( - 3, 8). You can determine this parameter by using our another best circumference calculator. Send feedback | Visit Wolfram|Alpha 55 ) Note the caveat: If you get the negative number on the right, then it was NOT a general form of an equation of a circle at all (sometimes they ask you to check this). Step 2: Click on the "Compute" button to compute the graph for the given center and radius of the circle. Note that for the general form of a circle's equation the first two coefficients are ones, and the free member could be assigned zero. The equation (x+9) + (y6) = 10 is in the standard circle equation form (xA) + (yB) = C, making A = 9 and B = 6. read my article on common questions about ellipses. r You can convert general form to standard form using the technique known as Completing the square. We know we eventually need to change the equation into the standard form of the equation of a sphere, (x2 + 16 8x) + (y2 + 4 4y) = 25. x2 + 16 8x + y2 + 4 4y 25 = 0. x2 + y2 8x 4y 5 = 0. 2 =55 r= Squaring the result gives us 62 = 36. Remember that to complete the square, we take half of the x coefficient and square the result, then add it to both sides. Rearrange the formula of F in terms of radius r: r= ( (D/2)+ (E/2)-F); and Solve the equation in step 3 to obtain the radius of the circle. The standard form of a circle is x2 x 2 plus y2 y 2 equals the radius squared r2 r 2. Add this calculator to your site and lets users to perform easy calculations.
