Find the length of the radius of the following circle. (x + 2) 2 + y2 = 10 5 √ (10) 100

For this case we have the following equation:

(x + 2) 2 + y2 = 10

We must remember that the standard equation of the circle is given by:

(x - h) 2 + (y - k) 2 = r2

Where r is the radius.

Therefore, in the given equation the radius is:

r ^ 2 = 10

Clearing we have:

R = root (10)

Answer:

The length of the radius of the circle is:

√ (10)
