Question

use the information provided to write the standard form equation Center: (9, 10) Radius: √22

​

Answer 1

Answer:  $(x-9)^2 + (y-10)^2 = 22$

Explanation:

The template for any circle is the form

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

with

• (h,k) = center
• r = radius

Plug in the given values to lead to the equation above.

Since the radius is $r = \sqrt{22}$, we square both sides to get $r^2 = (\sqrt{22})^2 = 22$. The square root goes away.
