Question

Find the equation of the circle whose center and radius are given.

center (0, 8), radius = 8

hartnn · Answer

Equation of circle : 
$\Large (x-h)^2 + (y-k)^2 = r^2 $

hartnn · Answer

with h,k as cetre, here h= 0, k=8
and r = radius = 8

anonymous · Answer

I'm supposed to fill in the blanks, they've already answered part of it.

anonymous · Answer

So here's what they've given me;

anonymous · Answer

__+(___)_______

anonymous · Answer

That's all they've said, so I have to figure out the rest =/

hartnn · Answer

what do you get after you plug in h=0, k= 8, r= 8 in the formula i gave you ?

anonymous · Answer

(x-0)^2+(y-8)^2=8^2

hartnn · Answer

yes,
simplifying that 
x^2+ (y-8)^2 = 64

does that help ypu fill all the blanks ?

anonymous · Answer

Ohh, that does indeed. Thank you so much! :) That makes sense now!

hartnn · Answer

you're most welcome ^_^
