First of all, you have to promise us that you're talking about a circle.
We're going to assume that, since you mentioned 'radius'.
The perimeter of a circle ... usually called its 'circumference' ... is (pi) x (the circle's diameter).
The circle's diameter is (2) x (its radius).
Diameter = 200 millimeters
Circumference = (pi) x (200) = 628.319 millimeters (rounded)

How do you find the radius of a circle with an area of 100 pie meters?
Use the equation: Area of Circle = pi * r^2 so... 100 pi = pi * r^2 The pi's cancel out. 100 = r^2 Square both sides to find the radius. square root(100) = r, the radius of the circle
