Q-00052173
If a circle has a center at (3, -2) and a radius of 5, what is the equation of the circle?
1
(x - 3)² + (y + 2)² = 25
2
(x + 3)² + (y - 2)² = 25
3
(x - 3)² + (y + 2) = 5
4
(x + 3) + (y - 2) = 25
Answer and Solution
Answer
A. (x - 3)² + (y + 2)² = 25
Solution:
Using (h, k) = (3, -2) and r = 5, the equation becomes (x - 3)² + (y + 2)² = 5², leading to (x - 3)² + (y + 2)² = 25.
