Circles

Parts of a Circle center radius

From this form, we can tell the center and radius 𝑥−4 2 + 𝑦+1 2 =25 𝑥 2 + 𝑦−2 2 =12

Write the equation of each circle. J with center J (-3, 2) and radius 4 K with center K (0, 0) and radius 𝟑 L with center L (9, 1) and radius 𝟐 𝟕

Graphing Circles Step 1- Rewrite equation in standard form Step 2- Identify the center and radius Step 3- Plot the center and then 4 more points (use the radius and count up, down, left, and right from center)

Graph the circles 𝑦 2 −9=− 𝑥 2
