Question

Find the center + radius of the circle:

Equation: (x+2)^2 + (y+10)^2 = 4

Answer 1

(-2;-10) i think

Answer 2

I'm sure agent0smith will explain why

Answer 3

\[\Large (x+2)^2 + (y+10)^2 = 4\]
This is the standard form of a circle, with center (h, k) and radius r.
\[\Large (x-h)^2 + (y-k)^2 = r^2\]
Now compare that to yours:
\[\Large \left( x-(-2) \right)^2 + \left( y- (-10)\right) ^2 = 2^2 \]

Answer 4

basically you have an equation:
(x-h)^2+(y-k)^2=r^2
and (h;k) is the center and r is the radius

Answer 5

thank you guys im really not that good in math

Answer 6

so it's -2 and - 10 and radius is 4?

Answer 7

Center is correct. Pay more attention to the r^2 in the equation above.

Answer 8

Center (-2, -10)

Answer 9

2?

Answer 10

Correct.
