<span>The answer would be C. A cross section is defined is the intersection of a plane in a three-dimensional space. Therefore, cutting a cross section perpendicular to a cylinder would result to a rectangle where the height is equal to the height of the cylinder and its width is same as the diameter of the cylinder base.</span>

Answer:
Step-by-step explanation:
We have that
x²<span>-6x+7=0
</span>Group terms that contain the same variable
(x²-6x)+7=0
Complete the square Remember to balance the equation
(x²-6x+9-9)+7=0
Rewrite as perfect squares
(x-3)²+7-9=0
(x-3)²-2=0
(x-3)²=2
(x-3)=(+/-)√2
x=(+/-)√2+3
the solutions are
x=√2+3
x=-√2+3
Since it's a square, the sides are all the same. This is going to be the equation.
S²=196
14×14=196
The length of one side is 14.
