Question

Form the equation of a circle with the given center and radius.

Center: (2, -3); radius: square root of 6
Equation of a circle (x - h)2 + (y - k)2 = r2

Answer 1

(x -2)² +(y +3)² = 6

Explanation:

Put the given numbers into the given formula and simplify. h = 2, k = -3.

(x -2)² +(y -(-3))² = (√6)²

(x -2)² +(y +3)² = 6
