Volume Formula [Cylinder]:
\displaystyle V = \pi r^2 h

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given variables</em>.

<em>h</em> = 5 cm

<em>r</em> = 10 cm

<u>Step 2: Find Volume</u>

  1. [Volume Formula - Cylinder] <em>Substitute</em> in variables:
    \displaystyle V = \pi (10 \ \text{cm})^2 (5 \ \text{cm})
  2. [Order of Operations] Evaluate:
    \displaystyle V = 500 \pi \ \text{cm}^3
  3. Approximate:
    \displaystyle V \approx \boxed{ 1570.8 \ \text{cm}^3 }

∴ the volume of a cylinder whose height is 5 cm and radius is 10 cm is <em>approximately</em> 1570.8 cm³.

HELP PLEASE 35 POINTS
postnew [5]

For this case we have:

Let a function of the form y = f (x)

By definition, to graph y = f (x + h), where h> 0, we must move the graph of f (x), h units to the left.

We observe that the red graph has the same form as the black graph, but it is displaced "h" units to the left.

It is observed that h = 3

So, if the black graph is given byy = f (x), the red graph is given by: y = f (x + 3)

Answer:

y = f (x + 3)

Option A
