Question

Write the equation of the circle The circle with center C(1, - 4) and radius r= 2

Answer 1

(x-1) ^2 + (y+4)^2 = 4

Explanation:

The equation of a circle can be written as

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

(x-1) ^2 + (y- -4)^2 = 2^2

(x-1) ^2 + (y+4)^2 = 4
