Question

Write an equation of the circle with center (7,-9) and radius 6

Answer 1

The answer to your question is (x - 7)² + (y + 9)² = 36

Explanation:

Data

Center = (7, -9)

radius = 6

Process

1.- Write the standard form of a circle

(x - h)² + (y - k)² = r²

2.- Identify the values of h, k and r

h = 7 k = - 9 r = 6

3.- Substitution

(x - 7)² + (y + 9)² = 6²

4.- Simplification

(x - 7)² + (y + 9)² = 36
