Given the center and radius of a circle, write the equation of the circle. Center: (-2, 1)

Radius = 5

(x + 2)² + (y - 1)² = 25

Circle Center Formula: (x - h)² + (y - k)² = r²

(h, k) is centerr is radius

Step-by-step explanation:

Step 1: Define

Identify variables

(h, k) = (-2, 1)

r = 5

Step 2: Find Equation

Substitute in variables [Circle Center Formula]:                                             (x - -2)² + (y - 1)² = 5²Simplify:                                                                                                             (x + 2)² + (y - 1)² = 25
