Write an equation in standard form for the circle?
elixir [45]

Answer:

<h2>(x - 3)² + (y - 5)² = 64</h2>

Step-by-step explanation:

The standard form of an equation of a circle:

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

(h, k) - center

r - radius

Look at the picture.

We have

center at (3, 5) → h = 3 anf k = 5

radius r = 8

Substitute:

(x-3)^2+(y-5)^2=8^2\\\\(x-3)^2+(y-5)^2=64
