Question

HELP Find the center and radius of the circle with the given equation. Then select the correct graph of the circle. x2 − 8x + y2 − 6y + 9 = 0 The center is located at (, ) and the radius is .

Answer 1

Centre: (4,3)

Radius: 4

Explanation:

h = -(-8)/2 = 4

k = -(-6)/2 = 3

4² + 3² - 9 = r²

r² = 16

r = 4
