R squared also called the coefficient of determination is the portion (%) of the total variation of the dependent variable that is explained by the variation in the independent variable. This is found by dividing the sum of squared regression (SSR) by the total sum of square errors (SST) that is R^2 = SSR / SST.
- When there is a perfect linear relationship between the variation of the dependent variable y and the variation of the independent variable x R^2 is equal to 1.
- The R^2 for any weaker linear relationships will range between 0 and 1 exclusive.
- Finally when there is no relationship between the variations of the y as a result of the variation in x R^2 is equal to 0.

What is the value of r³?
As in pie r squared? r = radius.
How do you convert the volume of a cylinder from squared to cubed?
Volume of any 3-dimensional object is always 'Cubic'. 'Squared' refers to area. The volume of a cylinder is V = pir^2h Where pi r^2 refers to the area of the circular profile of the cylinder., which is a 'squared' value/ 'h' is the height of the cylinder , which is a linear value. When a squared value is multiplied to a linear value , it becomes a cubic value.
What is r squared plus r squared?
r2+r2 = 2r2
