It depends on the capability of your computer.
In this web site, there are the text controls right above where I am typing my answer.
I will type r2, then select the '2' by itself, then click the x2 above the text box. Those two symbols, x2 and x2 are for subscript and superscript.
So, when done, r-squared is correctly displayed like this: r2.
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
That is the formula for the area of a circle; r refers to the radius, and pi is approximately 3.14. r squared means that you multiply r x r.
radius
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
On a computer, you can type the square of a number (let's say x) as x^2. For example, five squared is typed as 5^2.
You type alt-ctrl and the number 7
r2+r2 = 2r2
that is 14,519.4 squared
If r-squared = theta then r = ±sqrt(theta)
+r and -r
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
dependswhat's r
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
