radius 4(x+5)^2+4(y+4)^2-20=0

Lösung

radius

4 (x + 5)^{2} + 4 (y + 4)^{2} - 20 = 0

Lösung

r = 5

Schritte zur Lösung

4 (x + 5)^{2} + 4 (y + 4)^{2} - 20 = 0

Rewrite

4 (x + 5)^{2} + 4 (y + 4)^{2} - 20 = 0

in the form of the standard circle equation

(x - (- 5))^{2} + (y - (- 4))^{2} = (5)^{2}

Therefore the circle properties are:

(a, b) = (- 5, - 4), r = 5

And the radius is:

r = 5
