Question

which of the following correctly gives the center and radius of the circle defined by the equation (z-7)^2 = 10?

Answer 1

Center (7,2); Radius - Square Root of 10

Explanation:

Equation for a Cricle:

(x−h)^2 + (y−k)^2 = r^2

Where:

h = x-coordinate of the center of the circle

k = y-coordinate of the center of the circle

r = radius of the circle

For this problem, your h = 7, k = 2, and r = square root of 10
