Area and Volume Problems (Junior Cert Mathematics): Flashcards

Understand what's asked & which shapes are involved

Visualise shapes & label given dimensions clearly

Break down into simpler shapes (e.g. cylinder on cuboid)

All measurements must be in the same units

$V = \pi r^2 h$

Mathematical constant

Use $\pi$ exactly, not 3.14

Radius of the cylinder's base

Height of the cylinder

Radius is half of diameter: $r = \frac{d}{2}$

$cm^3$ (cubic centimetres)

$cm^2$ (square centimetres)
