Front
In the equation (x+3)²+(y-2)²=4, what is the center of the circle?
Back
The center of the circle is at (-3, 2).
2.
FLASHCARD QUESTION
Front
What is the standard form of a circle's equation?
Back
The standard form is (x-h)² + (y-k)² = r², where (h, k) is the center and r is the radius.

FLASHCARD QUESTION
Front
Determine the center and radius of the circle given by the equation: x² + y² + 10x - 8y - 8 = 0.
Back
Center C = (-5, 4), Radius r = 7.

FLASHCARD QUESTION
Front
In the equation (x-3)²+(y-2)²=16, what is the radius of the circle?
Back
The radius of the circle is 4 (since r² = 16).
