Write the equation of a circle with center (-2, 0) and area = 64 pi
kozerog [31]

Answer:

The required equation in standard form is (x+2)^2+y^2=64

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

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

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 64\pi

\pi r^2=64\pi

\implies r^2=64

We substitute these values into the formula to obtain;

(x--2)^2+(y-0)^2=64

We simplify to get;

(x+2)^2+y^2=64
