Equation of a Circle (Formula & Examples of Circle …
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. WebIn this case, r r is the distance between (2,7) ( 2, 7) and (−3,8) ( - 3, 8). Tap for more steps... r = √26 r = 26. (x−h)2 +(y−k)2 = r2 ( x - h) 2 + ( y - k) 2 = r 2 is the equation form for a … WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 … high school scholarships australia
