Question

Which is an equation of a circle with center (2, 7) and radius 4?
A. (x + 2)^2 + (y + 7)^2 = 4
B. (x - 7)^2 + (y - 2)^2 = 16
C. (x - 2)^2 + (y - 7)^2 = 4
D. (x – 2)^2 + (y - 7)^2 = 16

Answer 1

D.\[\left( x-h \right)^{2}+\left( y-k \right)^{2}=r ^{2}\]

with centre (h,k) and radius=r

Answer 2

I agree
