Question

Helppp!!!! please!!!

Answer 1

Answer:

I. (x - 6)² + (y + 7)² = 121

Step-by-step explanation:

Given a circle with coordinates of the center as (6, -7), and with a diameter of 22, equation of the circle is given below using the standard equation formula of a circle:

Formula => (x - a)² + (y - b)² = r²

Where,

a = 6

b = -7

r = radius of circle = ½ of diameter = ½ of 22 = 11

Thus, plug in the above values into the standard equation formula:

(x - 6)² + (y - (-7))² = 11²

(x - 6)² + (y + 7)² = 121

Our answer, which is the equation of the circle is I. (x - 6)² + (y + 7)² = 121
