What is the equation of a circle whose center is begin ordered pair negative 4 comma 6 end ordered pair and whose radius is 9 cm

solong [7]

Answer:

$(x+4)^2+(y-6)^2=81$

Step-by-step explanation:

We want to find equation of a circle with center (-4,6) and radius 9cm.

The equation of a circle with center (h,k) and radius $r$ units is given by;

$(x-h)^2+(y-k)^2=r^2$

We substitute the radius and the center to obtain;

$(x+4)^2+(y-6)^2=9^2$

The required equation is:

$(x+4)^2+(y-6)^2=81$
