to find the radius you have to measer trow the circle then divid by 2
The formula is 2pie(radius).
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
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 to find the radius it is diameter/2.
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".
you measuresit by the radius
Circumference=2*pi*radius
pie multiplied by the radius.
The formula to find area is you do the radius squared times pi or 3.14
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.
