Question

Find the length of the radius for this circle.

(x - 3)² + (y - 5)² = 8

Answer 1

(x-a)^2+(y-b)^2=radius^2

Answer 2

The standard form of a circle is:

\[(x-h)^2 + (y-k)^2 = r^2\]

So in this case, \(r^2\) = 8... What is r?

Answer 3

That's the general formula for a circle

Answer 4

2rad2 would be the legnth of the radius
