If you mean the just copy and paste this "Registere®d" symbol (®) and you're wanting to type it in Microsoft Word or something, the quickest way is to hold the "Alt" key down and type "0174" at the same time, then release the "Alt" key. I've found you must use the numbers on the side of the keyboard, rather than those across the top (or, on a laptop, you must turn on the num lock and use the keys under "u,i,o,j,k,l and 7,8,9). The shortcuts can be found in the Character Map in Windows under Start - All Programs - Accessories - System Tools. It give you the keyboard shortcuts for all sorts of symbols and characters (useful for accented characters etc..). If you don't use the character often, just copy/paste what you want from the Character Map. Hope this helps - ®.
It is r*sqrt(2) = 1.414*r, approx.

The radius of the circle decreases when you make the circle smaller.
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.

Consequently, the value of ( r^2 ) also decreases, resulting in a smaller circle. Thus, the number that decreases in the equation is ( r^2 ).

The number of square units occupied by the space inside a circle is called its area. The area ( A ) of a circle can be calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius of the circle. This means that the area depends on the square of the radius multiplied by the constant ( \pi ) (approximately 3.14).

Not if the whole segment is inside the circle.
