Definition

Cylinder = A cylinder is a 3D solid object usually with two identical circular shapes at each end connected by a curved surface.

Volume = Volume is a quantity of 3D space enclosed by a surface.

Example

How do you find the volume of a cylinder.

Find the volume of a cylinder with a height of 8 units and a radius of 5 units.

$r = \textcolor{#FF9933}5$r = \textcolor{#FF9933}5

$h = \textcolor{#00BFFF}8$h = \textcolor{#00BFFF}8

$V=\pi r^{2}h$

$V=\pi\cdot\textcolor{#FF9933}5^2\cdot\textcolor{#00BFFF}8$

$V=\pi\cdot25\cdot8$V=\pi\cdot25\cdot8

$V=\pi\cdot200$V=\pi\cdot200

$V=200\pi$V=200\pi

Great job!

V=\pi \textcolor{#FF9933}r^2\textcolor{#00BFFF}h
