Question

Find the equation of the circle whose center and radius are given.

center (0, 8), radius = 8

Answer 1

hint:

(x-h)^2+(y-k)^2=r^2 is the general equation of a circle where

(h,k) is the center

r is the radius

Answer 2

Im confused

Answer 3

what is the center in this case?

Answer 4

(0,8)

Answer 5

so (h,k) = (0,8)

which means

h = 0
k = 8

Answer 6

the radius is given to be 8, so r = 8

Answer 7

so whats the answer

Answer 8

plug in h = 0, k = 8 and r = 8 into (x-h)^2+(y-k)^2=r^2 to get your answer

Answer 9

i got it thanks
