Since people began using numbers for measuring lengths, they have wanted to find the square roots of those numbers. There are many situations in which a square root is needed. For instance, knowing the square root is useful if you want to find the length of the side of a square field ...
To find the sum of squares: Calculate the mean (average) of the data: this is equal to the sum of all data points divided by the number of data points Calculate the difference from the mean for each data point: Take each data point and subtract the mean from it Square the resulting ...
r is the radius of the circle, which is the distance squared (raised to the power of 2) from the circle's center to any point on its edge. So, to find the area of a circle, square the radius and multiply by pi. Learn & Test Your Skills ...
