Step-by-step explanation:
I guess the 3.14 is to be used for pi (and not r, which is what we need to find out).
the volume of a cylinder is ground area × height.
the ground area is the area of a circle, which is pi×r².
so, we have
pi×r²×height = 115 cm³
3.14×r²×7.7 = 115 cm³
3.14×r² = 14.93506494...
r² = 4.756390107...
r = 2.18091497... cm
Consider the given parallelogram KLMN.
Prove: 
Statement Reason
1.
Definition of parallelogram
2.
Same Side interior angle theorem


3.
Substitution property

4.
Subtraction property of equality

Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
5.
Angle Congruence Postulate

When two angles are equal, then they are said to be congruent by Angle congruence postulate.
Answer:
2/9
Step-by-step explanation:
We have 3 video games
I will assume that pirates have a water theme, so 2 have a water theme
That leaves 1 game with no water theme
P (no water theme) = games with no water theme/ total
=1/3
The games are 6 7 and 9 dollars
2 games are at least 7 dollars
P( at least 7 dollars) = games at least 7/ total
=2/3
P ( no water theme at least 7 dollars) = P (no water theme) * P( at least 7 dollars)
= 1/3*2/3
= 2/9
