In statistics, R2 (R-squared) indicates how closely a group of graphed points follow a straight line. Points that are closer to each other and the more they form a straight line, indicate a stronger relationship between the data points.
Here is a method you can use to find R2 with Excel:
- List two columns of numbers (need to be the same number of data points in each list).
- Find a location on the worksheet to insert a chart.
- Select the chart wizard and choose the standard XY (Scatter) chart.
- Follow the procedures to create the chart.
- Add a trend line to the chart, following the procedures of modifying the chart.
- Read R2 from the chart.

How do you find the value of h when pi times r to the second power times h divided by 3?
There is not enough information to answer the question as it is stated. If the value of pi*r2*h/3 is known (to be k, say) then h = 3*k/(pi*r2)
How do you find volume of cilinder?
The formula is π * r2 * h... Where π is the value of Pi, r is the radius of the cylinder and h is the height.
How do you find R2?
Under the home tab in the find and select group click find and select then click on the go to command. Then type go to R2 or on the top right of the spreadsheet there is a find command.. type r2.. its right beside the formula bar

How do you find the diameter of a circle if you have the area?
The formula A = (pi) r2 lets you find the radius, which is half of the diameter. Divide the area by pi, then take the square root of that value, which is the radius. Then multiply by 2 to get the diameter. -- Example: Area = 100 A = (pi) r2 100 = (3.1416) r2 r2 is 100/3.1416 or about 31.83, and the square root is 5.64 r = 5.64 and D = 11.28

What does the value of r square interpret?
R2 refers to the fraction of variance. it is the square of the correlation coefficient between two dependent variables. It is a statistical term that tells us how good one variable is at predicting another. If R2 is 1.0, then given the value of one variable you can perfectly predict the value of the other variable. If R2 is 0.0, then knowing either variable does not help you predict the other variable. In turn, the higher the R2 value the more correlation there is between the two variables.

2 resistors are connected equivalent resistance in parallel is 2 and equivalent resistance in series is 2 find the value of 2 resistors?
R1+ R2 = 2 (1)1/R1 + 1/R2 =1/2 => R1 x R2 /(R1 +R2) = 2 (2)(1) and (2) => R1 x R2 / 2 = 2 => R1 x R2 = 4 => R1 = 4 / R2 (3) (1) and (3) => 4/R2 + R2 =2 => 4 + R2 2 = 2 R2 => R22 - 2R2 + 4 =0 (4)delta = (-2)2- 4 *4 = -12 delta is negative which means that the equation's solution has an imaginary part,hence no real solution for the equation
How do you find the radius of a circle if you have area?
The area of a circle is pi * r2 where r is the radius Solving for r, where A is the area: A = pi * r2 A/pi = r2 r = sqrt(A/pi)

How do you find the area of circle with the radius?
Area = pi R2
How do you find the height of a cylinder?
The formula for the volume of a cylinder, which is h(pi)r2, is the area of the base (pi)r2 multiplied by the height (h). If you are given the diameter instead, remember that the diameter is twice the radius.So if we know that V = h(pi)r2, we can rearrange the formula in order to find the height.Divide the whole equation by (pi)r2. The result is: V ÷ (pi)r2 = h OR h = V ÷ (pi)r2.The formula h = V ÷ (pi)r2 means the height (h) is equal to the volume (V) divided by the area of the base (pi)r2.
