Question

Whats the center and radius of (x+3)^2+(y-5)^2=64

Answer 1

The answer to your question is Center = (-3, 5) radius = 8

Explanation:

Data

(x + 3)² + (y - 5)² = 64

Process

Because of the characteristics of the equation, we conclude that it is a circle.

Standard form of a circle:

(x - h)² + (y - k)² = r²

In this form of the equation, the center has coordinates (h, k), just change the signs.

And to get the radius, just get the square root of r²

h = -3

k = 5

r = 8

Center = (-3, 5)

radius = 8
