WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 … WebFree Circle Center calculator - Calculate circle center given equation step-by-step

WebApr 27, 2016 · The equation of a circle with center #(h,k)# and radius #r# is: #r^2=(x-h)^2+(y-k)^2# We are told that the center of this circle is #(2,4)#, so #r^2=(x-2)^2+(y-4)^2# However, we don't know the radius of this circle. Luckily, we are also told that this circle contains the point #(-2,1)#, so we will use that information to find #r#: #r^2=(x-2)^2 ... WebThe horizontal and vertical translations represent the center of the circle. The formula is derived from the distance formula where the distance between the center and every point on the circle is equal to the length of the radius. Step 2.
