Question

17.1 equation of a circle evaluate homework and practice answer key

Answer 1

The evaluation using the equation of circle for the practice question is (x - 4)² + (y + 11)² = 256

What is the equation of the Circle Distance Formula?

With respect to the distance formula, a point location in space (x,y) at a distance (r) from the origin is valid if $\mathbf{\sqrt{x^2 + y^2} = r}$. Hence this refers to the equation of the circle centered at the origin.

For Conic Sections:

• $\mathbf{(x-h)^2 (y-k)^2 = r }$

where;

• center = (h,k)
• radius = r

Let's assume we have a circle with C(4,-11) and radius r = 16;

Then, we have:

(x-h)² +(y -k)² = r²

(x-4)² + (y - (-11))² = 16²

(x - 4)² + (y + 11)² = 256
