Net of a Cone (Leaving Cert Mathematics): Flashcards

A 2D representation of a 3D solid laid flat

Circular base and curved surface tapering to a point

One circle (base) and one sector (curved surface)

Base of the cone

Curved surface of the cone

Slant height of the cone

Radius of the base

Slant height (radius of larger circle/sector)

$\theta = \frac{r}{l} \times 360^\circ$

$\pi r^2$

$\pi r l$

$\pi r^2 + \pi r l$
