Question

The equation of a circle is shown below.

(x -5)2 + (y + 2)2 = 64
The radius of the circle is ________ units

Answer 1

there is no pic :[

Answer 2

8

Answer 3

cool i thought it was going to be 6 or 9

Answer 4

@SNSDYoona explain to Tamatchi u u got 8

Answer 5

ohh ok.
I got 8 because i square root 64

Answer 6

oh ok then i dont think i did that :]

Answer 7

the circle equation is (x+h)^2 + (y+d)^2 = r^2
h and d are the x and y coordinates and r is the radius of the circle

Answer 8

nice :)
exaplain how u get the asnwer :)

Answer 9

i no from there

Answer 10

i didnt sqr root it

Answer 11

i just wanted to double check my answer

Answer 12

You should correct this:
the circle equation is (x+h)^2 + (y+d)^2 = r^2

if (h,k) are the center of the circle, the equation should read
(x-h)^2 + (y-k)^2 = r^2

Answer 13

depends if h and k are negative or positive x n y values

Answer 14

yea i shud have put (x-h)^2 + (y-k)^2 = r^2

Answer 15

would it give you the same answer

Answer 16

umm yea

Answer 17

im very good in science math is m weakness y

Answer 18

wait u have to square root it o.O

Answer 19
