Volume of Cylinders and Spheres (HSC SSCE Mathematics Standard): Flashcards

$V = pi r^2 h$

Radius ($r$) and height ($h$)

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

$V = \frac{2}{3}\pi r^3$

Ring shape - circle with circular hole in middle

Divide by 2

Cubic units (mm³, cm³, m³)

$A = \pi(R^2 - r^2)$

Area of circular base × height

Hemisphere is exactly half of sphere volume
