The circle passes through the point (−2, 3) with a center of (-4,6). What is its radius?

Ganezh [65]

Answer:

radius = √13

Step-by-step explanation:

Forming the equation :

(x - h)² + (y - k)² = r²

(x, y) = point on circle
(h, k) = center of circle
r = radius

Solving :

(-2 + 4)² + (3 - 6)² = r²
r² = 4 + 9
radius = √13
