2 squared is 4
3 cubed is 27
27 plus 4 is 31
If: r2 = 17 Then: r = the square root of 17
V = (pi) R2 hDivide each side of the equation by (pi)R2 :h = V/(pi)R2
pi times radius or diameter equals are of a cirlce
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.
The area of a circle is pi r2 If r = 3, that makes the area roughly 28.27
The quadratic expression: r2+10r+25 = (r+5)(r+5) when factorised
r -31
It's an incorrect statement. 5 plus 6 equals plus 11. Also, pi R round, cornbread R2 .
x2 + y2 = 2r2
X2 + y2 = 100 = r2 r = 10
R2 - 16 = 0 R2 = 16 Take the square root of each side to get rid of the square on R. R = 4
If: r2 = 17 Then: r = the square root of 17
r2+r2 = 2r2
2x plus 6y equals 32 32 divided by 6= 5 R2 5+2= 7x6= 42-5=37-2=35 so X=5
x2 +y2 = R2 =16 = radius 2 R = 4
The question cannot be solved because, thanks to shortcomings of the browser that is used for posting questions on WA, there is no equals symbol. I suggest you resubmit using words like plus, minus, equals to get around the browser problems.
The LCM is r^3 + 9r^2 - 25r - 225.
