Conic Sections - Circles

Write the equation of the circle

Identify the center of the circle:

$$\left(x+7\right)^2+\left(y+8\right)^2=64$$

(a)  

Identify the radius of the circle:

$$\left(x+7\right)^2+\left(y+8\right)^2=64$$

Identify the center of the circle:

$$x^2+\left(y+2\right)^2=121$$

(a)  

Identify the radius of the circle:

$$x^2+\left(y+2\right)^2=121$$

Find the center of the circle:

$$x^2+y^2+24x+10y+160=0$$

(a)  

Find the radius of the circle:

$$x^2+y^2+24x+10y+160=0$$

Find the center of the circle:

$$-6x+x^2=97+10y-y^2$$

(a)  

Find the radius of the circle:

$$-6x+x^2=97+10y-y^2$$

Write the equation of a circle in standard form:

$$137+6y=-y^2-x^2-24x$$
