Write the following equation of the circle in general form that will satisfy the given conditions
2. the center is at (-3,2), and the circle passes through (4,-6).
Answer:
x² + y² + 6x - 4y - 100 = 0
Step-by-step explanation:
write the following equation of the circle in general form that will satisfy the given conditions
2. the center is at (-3,2), and the circle passes through (4,-6).
first, find the radius
use distance formula (center to a point that the circle passes)
d = √(x2 - x1)² + (y2 -y1)²
d = √(4 - -3)² + (-6 - 2)²
d = √113
r = √113
Standard form: (x-h)² + (y-k)² = r²
where h and k are the coordinates of the center of the circle
(x - -3)² + (y - 2)² = (√113)²
(x + 3)² + (y - 2)² = 113
x² + 6x + 9 + y² - 4y + 4 - 113 = 0
x² + y² + 6x - 4y - 100 = 0
