Why do you square the deviations and then turn around and find the square root of the sum of the squares?

If you simply added the deviations, their sum would always be zero. The derived statistic would not add any information. Essentially, the choice was between summing the absolute values or taking the square root of the squares.
The latter has some very useful statistical properties.

How do you find the area of a square if you have the circumferince?
you can't have circumference with a square. if the have the perimeter(the distance around it) you divide it by four then multiply it by two. this only works with squares, not rectangles.
How do you find the area of a circle inside a square?
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area

How do you solve imperfect squares?
u cant get the excat answer but if you want 1) To find imperfect squares you estimate the square to the nearest integer 85 2) This is an imperfect square because no whole number multiplies itself to equal 85 you find the closest square but less than the imperfect squares answer 9*9=81 4) Now you find a square that is closest higher than the imperfect squares answer 10*10=100 5) So 85 lays between 9 and 10
How do you find the sum of squared deviations in a set of numbers?
It would be useful to know what the deviations were from.
How to find the diameter of a cube?
the square root of the sum of the squares of three perpendicular edges.
How do you find the total area of joined squares?
To find the area of joined squares, add up the area of each individual square. For instance, I have a square with a side length of 5 attached to another square with a side length of 2 A = 52 + 22 = 25 + 4 = 29 units2
