Write the equation of the circle with center (2, - 3) and a radius of 4.

A) (x + 2) ^2 + (y - 3) ^2 = 4

B) (x - 2) ^2 + (y + 3) ^2 = 4

C) (x + 2) ^2 + (y - 3) ^2 = 16

D) (x - 2) ^2 + (y + 3) ^2 = 16

Luz Mendez · Answer 1

C (h, k) radius (r)

C (2,-3) r=4

(x-h) ^2 + (y-k) ^2 = r^2

(x-2) ^2 + (y--3) ^2 = 4^2

(x-2) ^2 + (y+3) ^2 = 16

therefore, the answer is D
