In MS-Word, you can type (r). It should automatically be converted to the "registered trademark" symbol, by Word's autocorrect feature. You can also use the "Insert Symbol" command - or, if you use Windows, open the CharMap application, find the symbol, then use copy & paste.
A little R in a circle usually means "registered trademark".
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
The area of a circle is the number of square units inside that circle, if each square in the circle to the left has an area of 1cm2, you could count the total number of squares to get the area of this circle. However, it is easier to use one the following formulas; A=.r²or A=pi times r times r, where A is the area and r is the radius.
In the standard equation for a circle centered at the origin, ( x^2 + y^2 = r^2 ), the radius ( r ) determines the size of the circle. When you make the circle smaller, the radius ( r ) decreases, which in turn causes ( r^2 ) to decrease as well. Thus, the value of ( r^2 ) in the equation decreases when the circle is made smaller.
You are describing a railroad crossing sign.

It is r*sqrt(2) = 1.414*r, approx.

R = radius of big circle, r = radius of little circle Area of circle = pi x R x R = 4 x pi x r x r = 4 x pi x 3 x 3 Therefore R x R = 36 and so R = 6 inches
The radius of the circle decreases when you make the circle smaller.

3.14 x (r x r) 9 foot diameter circle
In the standard equation of a circle centered at the origin, (x^2 + y^2 = r^2), the number that changes when you make the circle bigger or smaller is (r^2), where (r) is the radius of the circle. As you increase or decrease the radius, (r^2) will correspondingly increase or decrease. The values of (x) and (y) remain constant as they represent points on the circle.
