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
