Question

Find the center and radius of the circle: (x+9)^2+(y-6)^2=25

Answer 1

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

(h, k) is the center.

r is the radius.

(h, k) in the given equation is (-9, 6). This is the center.

We need to take the square root of 25 since the formula has r^2.

√25 = 5

So, the radius is 5.

Best of Luck!

Answer 2

The center is (-9,6) and the radius is 5

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-6)^2=5^2

The center is (-9,6) and the radius is 5
