Right Prisms and Cylinders (Grade 11 NSC Matric Mathematics): Flashcards

3D solid with polygon base, vertical sides perpendicular to base

Angles between base and sides are 90° (right angles)

Total area of all exposed outer surfaces of 3D object

All faces of 3D shape laid out flat in 2D

$2 imes$ (area of base) $+$ (area of all side faces)

$2pi r(r + h)$

3D space occupied by object or amount it can contain

Area of base $imes$ height

$V = pi r^2 h$

Diameter $= 2 imes$ radius
