Question

Circle S has an equation of (x – 16)2 + (y + 9)2 = 4. What is the center and radius of circle S?

Center: (16, -9); Radius: 4

Center: (-16, 9); Radius: 2

Center: (16, -9); Radius: 2

Center: (-16, 9); Radius: 4

Answer 1

write the equation in general form

Answer 2

is it b?

Answer 3

it is 1...because u must change the signs

Answer 4

it is the third one

Answer 5

The general equation of a circle is (x-a)^2 +(y-b)^2 = r^2

Center is (a,b)
Radius = r

Answer 6

oh,yeah @beketso is correct

Answer 7

3

Answer 8

From the equation you have: (x-16)^2+(y-(-9))^2=2^2

the correct answer is :
center: (16, -9)
radius: 2

Answer 9

so is it 1 or 3 O.o
