Answer:
Volume of Cylinder=πr²h
22/7*2/1*2/1*5/1=
440/7=62.857 to nearest tenth
62.860, if u like u put the zero.
5(r - 10) = -51
= 5r - 50 = -51
= 5r = -51 + 50
= 5r = -1
= r = -1/5
r = -0.2
Step-by-step explanation:
Which one is the height?¿
The formula is
b1+b2 divided by 2 times the height
That's the best I can do for you atm atleast.
First isolate the "y" in the equation.
2y - x = -12 Add x on both sides
2y - x + x = -12 + x
2y = -12 + x Divide 2 on both sides to get "y" by itself


Your slope is
.
For the equation of the line to be parallel to the given equation, the slopes have to be the same. So the parallel line's slope is also 
y = mx + b

To find "b", you plug in the point (18,2) into the equation


2 = 9 + b Subtract 9 on both sides
2 - 9 = 9 - 9 + b
-7 = b
Your equation is:

Give a algebraic expression for the number of non overlapping triangles in a polygon that has "n" sides
