Answer:

Radius of the circle = 10

Step-by-step explanation:

The equation for the circle below is x2 + y2 = 100.

The equation of a circle in center radius form is

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

The given equation can be written as

[tex](x-0)^2 + (y-0)^2 = 100[/tex]

from the above equation

r^2 = 100

take square on both sides

r=10
