Area and Volume Formulae (Junior Cert Mathematics): Flashcards

$A = L^2$

$P = 4L$

$A = L \times W$

$P = 2L + 2W$

$A = \frac{1}{2} \times b \times h$

$A = \pi r^2$

$C = 2\pi r$

$A = b \times h$

$V = \pi r^2 h$

$V = L^3$

$V = L \times W \times H$

$V = \frac{4}{3} \pi r^3$

$V = A \times h$ (where $A$ = area of base)

CSA: sides only; TSA: all surfaces
