Which is an equation of a circle with center (-10, 6) and radius 8?

A: (x + 10)2 + (y - 6)2 = 8

B: (x + 10)2 + (y - 6)2 = 64

C: (x - 6)2 + (y + 10)2 = 64

D: (x - 10)2 + (y + 6)2 = 8

Answer 1

The answer to your question is letter B.

Explanation:

Data

Center = (-10, 6)

radius = 8

Process

1.- To find the answer to your question just substitute the values in the standard form of the circle.

Equation

(x - h)² + (y - k)² = r²

h = -10

k = 6

r = 8

Substitution

(x + 10)² + (y - 6)² = 8²

Simplification

(x + 10)² + (y - 6)² = 64
