to find the radius you have to measer trow the circle then divid by 2
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
The formula is 2pie(radius).
Circumference=2*pi*radius
The formula to find area is you do the radius squared times pi or 3.14
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.

Well the formula for the radius of the square is radius squared * pi (3.14)So find the radius (which is half of the diameter. which is exactly half of the shape)and do the formula. end the answer with "m".
Well to find the radius it is diameter/2.
you measuresit by the radius
Circumference=2*pi*radius
pie multiplied by the radius.

this is called finding the circumference. The formula is 2*pie*radius
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
