Question

What is the equation of a circle with center (-7,4) and radius 8?

A. (x - 7)2 + (y + 4)2 = 8
B. (x + 7)2 + (y - 4)2 = 64
C. (x + 7)2 + (y - 4)2 = 8
D. (x - 7)2 + (y + 4)2 = 64

Answer 1

the answer is b, switch the coordinate signs and then square the 8 because it’s square rooted to get the radius

Answer 2

The answer to this question is
B. (x+7)²+(y-4)²=64

I hope this helps!!!!!!!
