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.
You are describing a railroad crossing sign.
To circle a horse you have to pull on the inside rein and make a zero sort of
stronger. easy.
Not if the whole segment is inside the circle.
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.
If 5 circles are inside the one circle, then the periphery is of the one circle. The periphery depends on the diameter of the one circle. The number of circles inside won't make any difference.
