Mensuration (AQA GCSE Further Maths): Flashcards

Measuring geometric figures and calculating areas, perimeters, and volumes

$\frac{1}{2} \times \text{base} \times \text{height}$

Perpendicular distance from base to opposite vertex

$\text{base} \times \text{height}$

$\frac{1}{2}(a+b)h$ where $a$ and $b$ are parallel sides, $h$ is height

$\pi d$ where $d$ is diameter

$2\pi r$ where $r$ is radius

$\pi r^2$ where $r$ is radius

$d = 2r$ (diameter is twice the radius)

Area of cross section $\times$ length

Has constant cross-section along its length

Cuboids, triangular prisms, cylinders

Break into simpler shapes, then add or subtract areas

Must be consistent throughout calculation; convert if needed
