Question

1. Write the equation of a circle with center (5, -2) and r = 8.

Answer 1

Answer:

(x-5)^2 + (y+2)^2 = 64

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center of a circle and r is the radius.

(x-5)^2 + (y- -2)^2 = 8^2

(x-5)^2 + (y+2)^2 = 8^2

(x-5)^2 + (y+2)^2 = 64
