Web23 sep. 2024 · 1) the radius of the green circle equals the radius of the red one: in the original post I understood that the diameter is P1-P5, so I calculated the radius as R = sqrt(sum((P5-P1).^2))/2; 2) The key of the method is to create the green circle in a local reference frame (simple in local coordinates, e.g. x-y plane, centered) then rotate … 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 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4. definition of dwarf planets
