π (pi). If you square pi and take the square root of that, you get pi. If you take the square root of pi and square that, you again get pi.

The general answer to "What is the square root of x squared?", where x is any real number, is x itself -- but depending on where you put the implicit parentheses (whether you square first or take the square root first) the intermediate value may be an imaginary number.

Pi cannot be represented by an exact decimal (because it cannot be represented by a fraction, which is what "irrational" means in mathematics), but the beginning is 3.141592653589793238462643383279502884197. For more digits and more info, see Wikipedia's article on "Pi" is useful.

Edit:

All true except for one minor point: The mathematical answer to "What is the square root of x squared?" is not x itself. It is +x OR -x. So, the square root of pi squared is + pi or -pi

How do you find the radius of a circle if area is 81 pi?

Divide the 81 pi by pi, then square root it. (Use the formula for area of circle, which gives 81pi=pi*radius squared, but rearrange to find the radius). i.e. it's the square root of 81

If the area of a circle is 25 square units what is the radius of the circle?

area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821


How do you find the diameter of a circle if they give you the area?

Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)


What is the smallest perimeter for a shape with the area of sixty Meters squared?

The smallest perimeter for any area is achieved with a circle. The area formula for a circle is A = pi * radius squared. Where pi is a constant equal to about 3.14. In this case, 60 = pi * radius squared, then radius = square root (60 / pi) A circle's perimeter is called the circumference: C = 2 * r * pi So, C = 2 * square root (60 / pi) * pi It is approximately 27.5 meters


What is the radius of a circle if the area is 225?

The area is equal to pi times the radius squared, so dividing both sides by pi and taking the square root of both sides, we get that the radius is equal to the square root of 225/pi, or about 8.463.

divide the square feet by pi that gives you the radius squared find the square root and get the radius


How do you find diameter of a circle with the area of 8in pi cm squared?

You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.
