3. x² +(y + 2)2 = 64 Center: Radius:
2 answers:
Answer:
Center: (0, -2)
radius: 8
Explanation:
<u>Given equation</u>: x² + (y + 2)² = 64
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) are points of center. r denotes radius
So rewrite the equation in circle formula:
x² +(y + 2)² = 64
(x- 0)² +(y + 2)² = 8²
Identify followings:
h = 0, k = -2, radius = 8
