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.
To circle a horse you have to pull on the inside rein and make a zero sort of
You are describing a railroad crossing sign.
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.
Consider a circle of radius r. You want a square inside of that circle. The diameter of the circle is 2r and this is also the length of the diagonal of the square. Now the Pythagorean theorem says that if the side of the square inside the circle is of length s. 2s2 =4r2 this come for a2 +b2 =c2 where a and b are s and c is 2r so we have s2 =2r2 Then length of the side OS the square is r(square root of 2) or s=r(square root of 2)
