The answer is 16 inches.
Let r be a radius and h be a height of a cylinder
Since the cylinders are similar, then the ratio between their radiuses is equal to the ratio of their heights:
r1 : r2 = h1 : h2
Cylinder A:
r1 = 5.6 in
h1 = ?
Cylinder B:
r2 = 1.4 in
h2 = 4 in
5.6 : 1.4 = h1 : 4
h1 = 4 * 5.6 : 1.4
h1 = 16 inches
Turn the mixed number into an improper fraction, than multiply regularly. If it's an improper fraction than divide the top number by the bottom
11x - 3 = x - 13
-x -x
10x - 3 = -13
+13 +13
10x = 10

10 10
x = 1
The model (x+a)(x-a) will represents the factors of 4x²-9 as (2x+3)(2x-3).
<h3>What are the quadratic equations in one variable completing the squares method?</h3>
The "completing the squares" method aims to construct a quadratic equation of the form where the x variable is entirely covered by a single squared term, which is the square of a linear expression in x, as the name suggests.
The quadratic equation can resemble this:
x²-a² = (x+a)(x-a)
Given equation;
⇒4x²-9
⇒(2x)²-3²
The equation can be modeled as;
(2x+3)(2x-3)
Hence the model (x+a)(x-b) will represents the factors of 4x²-9 as (2x+3)(2x-3).
