Shape Volumes and Surface Areas

Circle Area

A = πr²

Circle Circumference

(Take derivative of area)

C = 2πr

Rectangle Area

A = LW

Rectangle Perimeter

P = 2L + 2W

Triangle Area

A = ½bh

Sphere Volume

V = 4/3 πr³

Sphere Surface Area

(Differentiate sphere volume)

SA = 4πr²

Cone Volume

V = 1/3 πr²h

Cylinder Volume

V = πr²h

Cylinder Surface Area

SA = 2πr² + 2πrh

Cube Volume

V = LWH

or V=a³

Cube Surface Area

SA = 6s²

Trough Volume

V = (base area)(height)
