The volume of a cylinder is given by the formula y
goblinko [34]
<h2>The volume of a cylinder (y) = \pi (x^2-6x+9) (2x+7)</h2>

Step-by-step explanation:

Given by question,

The volume of a cylinder = y, The radius of a cylinder(r)  = x - 3 and

The height of a cylinder(h)  = 2x + 7

To find, the volume of a cylinder (y) = ?

We know that,

The volume of a cylinder = \pi r^2 h

⇒ y = \pi (x-3)^2 (2x+7)

⇒  y = \pi (x^2-6x+9) (2x+7)

⇒  y = \pi (x^2-6x+9) (2x+7)

∴ The volume of a cylinder (y) = \pi (x^2-6x+9) (2x+7)

Thus, the volume of a cylinder (y) = \pi (x^2-6x+9) (2x+7)

maw [93]

Following the setps we have that

\begin{gathered} n\cdot n=64 \\ n^2=64 \\ n=\sqrt[]{64}=8 \end{gathered}

the lengths of the sides of the original square is 8 inches each one. Now we are going to find the lengths of the sides of the new square following the step 2

8\cdot\frac{3}{2}=\frac{24}{2}=12

the lengths of the sides of new square is 12 inches each one.
