1. which is the equation of a circle with center (–2, 3) and radius r = 5?
(x + 2)² + (y – 3)² = 10
(x + 2)² + (y – 3)² = 25
(x – 2)² + (y + 3)² = 10
(x – 2)² + (y + 3)² = 25
2. a circle with center (–1, 2) passes through point (2, –2). which is true?
the radius is.
the diameter is 10.
the equation is (x + 1)² + (y – 2)² = 10.
the circumference is 25.
4. which is the equation of a circle with diameterwith a(5, 4) and b(–1, –4)?
(x – 5)² + (y – 4)² = 10
(x + 5)² + (y + 4)² = 100
(x – 2)² + y² = 25
(x + 2)² + y² = 5
