<u>Geometry</u>

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.
