Question

What’s the equation if the center of the circle is (-7, 1) with a radius of 15 and how do I show the work

Answer 1

we know that

The equation of the circle in center radius form is equal to

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

where

(h,k) is the center

r is the radius

In this problem we have

(h,k)=(-7,1)

r=15

substitute the given
