Use the elimination method.
(-5x + y = 26)7
2x - 7y = 16
-35x + 7y = 182
2x - 7y = 16
-33x = 198
x = -6
Substitiute -6 for x in one of the equations.
2x -7y = 16
2(-6) - 7y = 16
-12 - 7y =16
-7y = 28
y = -4
The ordered pair would be (-6,-4)
Since the circle is inside the square, the diameter of the circle is the same length as a side of the square.
The length of the side of the square is found by taking the square root of the area:
Side length = SQRT(144) = 12 m
The circumference of a circle is found by multiplying the diameter by PI:
12 x 3.14 = 37.68 = 37.7 m
There are 7 tens, so i want to say 10^7
10 to the seventh power
Hey!
Now it is in fact possible for an equation to have no solutions or infinite solutions.
An equation getting infinite solutions would mean that you could choose any number for the variable ( ex. x or y ), and that number would make the equation true. To represent an equation with infinite solutions we'd use the infinite symbol.
An equation getting no solutions would just that. It would mean the equation has no solutions what so ever. You could plug in any number for the variable and every single time you would get no solution. In addition to the equation having no solutions, this would also mean that the equation is not true can never be true. To represent an equation with no solutions, we'd use a symbol that is a zero with a diagonal line through it.
Hope this helps!

Answer:
h ~ 4.974
Step-by-step explanation:
The formula for the volume of a cylinder is;
Where represents the value,
represents the radius of the given cylinder. In other words, if one were to take a base (the flat side in the case of the cylinder) of the figure. The distance from the center to a point on the outside of the circle is the radius.
represents the height of the object. In other words the distance between the two bases of the cylinder.
represents the volume, in other words, the space that the object takes up.
In this problem, one is given the diameter of the cylinder and the volume. One is asked to find the area.
The diameter of a circle is the distance between two opposite sides of the circle. The diameter will always pass through the center of the circle. To find the radius when given the diameter, one will divide by 2.
To solve this problem, one will substitute in the given information and solve for the height using inverse operations.
