The formula for radius is 
.
First we need to see what 8*π is, put it in your calculator and you will get . So now we know the exact circumference, so now put that into the equation to find the radius.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

Answer:
The system of equations is the option A
Step-by-step explanation:
Let
x ------> the number of tickets for the roller-coaster
y ------> the number of tickets for the bumper
z ------> the number of tickets for the Ferris wheel
we know that
The system of equations is equal to
<em>John</em>
2x+3y+z=42
<em>Darren</em>
3x+y+2z=36
<em>Shelley</em>
x+2y+3z=32
therefore
The system of equations is the option A
Answer:
(-8,1)
Step-by-step explanation:
Answer:
Step-by-step explanation:
y - x = -5
y = x-5
y = 2x² - 3x - 5
x-5 = 2x² - 3x - 5
2x² - 4x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2, 0
(x,y) = (2,-3), (0,-5)

Answer:
6. x = 3
8. x = -7.5
Step-by-step explanation:
Put the number in place of the expression it is equal to, then solve for x.
__
6) g(x) = -x +5
2 = -x +5 . . . . . . . . . g(x) is replaced by 2, because g(x) = 2
x +2 = 5 . . . . . . . . . . add x to both sides
x = 3 . . . . . . . . . . . . . subtract 2 from both sides
__
8) n(x) = -2x -21
-6 = -2x -21 . . . . . n(x) is replaced by its equal: -6
3 = x +10.5 . . . . . . divide both sides by -2
-7.5 = x . . . . . . . . . subtract 10.5 from both sides

<em>Additional comment</em>
We have shown a couple of ways these equations can be solved. You can separate the x-term and the constant terms before you divide by the x-coefficient, or you can do it after. In the first equation, we could have solved it ...
2 -x +5
-3 = -x . . . . subtract 5
3 = x . . . . . . multiply by -1
The way we did it avoids negative numbers.
