Question

What is the center and radius of the following circle: x2 + (y – 6)2 = 50
A. C (6, 0), r = 7. 07
B. C (0, -6), r = 7. 07
C. C (0, 6), r = 50
D. C (0, 6), r = 7. 07

Answer 1

(x-h)^2+(y-k)^2=r^2
(h,k) is center
r is radius
(h,k)=(0,6)
r=sqrt(50)

Answer 2

so is it C?

Answer 3

no, does sqrt(50)=50?

Answer 4

yea?

Answer 5

\[\sqrt{50}=50?\]

Answer 6

D

Answer 7

oh never mind it doesnt

Answer 8

\[\sqrt{50} \approx 7.07\]
