I checked everything is correct it's 6

Helena · Answer 2

6

Step-by-step explanation:

The 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

(x+5) ^2 + (y-7) ^2 = 36

Rewriting

(x+5) ^2 + (y-7) ^2=6^2

The center is at (-5,7) and the radius is 6

If the equation of a circle is (x+5) 2 + (x-7) 2=36, its radius is

If the equation of a circle is (x+5) 2 + (x-7) 2=

36, its radius is
