Question

Write the standard equation for the circle center (6, 7), r = 9.

Answer 1

`(x-6)^(2) +(y-7)^(2) =81`

Explanation:

The general equation for a circle is

`(x-h)^(2)+(y-k)^(2)=r^(2)` where (h,k) is the center of the circle and r is the radius

Plug in the (6,7) for the center and 9 for r
