Question

Help me it seems super easy tho.

Answer 1

Answer:

The center is (9,4) and the radius is 6

Step-by-step explanation:

We can write the equation of a circle as

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

(x-9)^2 + (y-4)^2 = 36

(x-9)^2 + (y-4)^2 = 6^2

The center is (9,4) and the radius is 6

Answer 2

Answer:

Step-by-step explanation:

X^2-9^2+y^2-4^2=36

x^2-81+y^2-16=36

x^2+y^2-81-16=36

x^2+y^2-97=36

x^2+y^2=36+97

x^2+y^2=133

x=$-\sqrt{-y^{2} +133}$
