    Answer: 10 units.

    Step-by-step explanation:

    The equation of the circle in Center-radius form is:

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

    Where the center is (h,k) and “r” is the radius.

    The equation of the circle given is:

    x ^2 + y^2 = 100

    You can observe that is written in Center-radius form.

    Then, you can identify that:

    r^2=100

    Knowing this, you need to solve for “r” to find the lenght of the radius.

    This is:

    r=\sqrt{100}\\\\r=10

    Therefore, the lenght of the radius is 10 units.
