Find the length of the radius of the following circle.

(x + 2)2 + y2 = 10

5
√(10)
100

Answer 1

The rule for the equation of a circle is x^2+y^2=r^2.
So if you have x^2+y^2=36, just squareroot the 36 and you'll have your radius. In this case, the radius is 6.

Answer 2

did this help u

Answer 3

so its 5

Answer 4

Answer 7

okay i get it thanks :) medal for you:)

Answer 8

ty

Answer 9

could you help me with this one

Find the coordinates of the center of the following circle.

(x + 3)2 + (y - 6)2 = 24

(-3,6)
(3,-6)
(6,-3)

Answer 10

ok
Equation of a circle with center at (h, k) id given by
(x - h)² + (y - k)² = r², where r is the radius of the circle
Now, (x + 3)² + (y - 6)² = 24
shows that the center is at (h, k) = (- 3, 6) .
