Square, side S:

Area = S²

Perimeter = 4 x S

Diagonal = S x sqr(2)

Cube, side S

Volume = S³

Surface Area = 6 x S²

Circle, radius R

Area = PI x R²

Circumference = 2 x PI x R

Sphere, radius R

Volume = 4/3 x PI x R³

Surface Area = 4 x PI x R²

Triangle, base B, perpendicular height H

Area = B x H / 2

Cone, base radius R, height H

Volume = PI x R² * H / 2

Length of sloping surface (base edge to top) = L = sqr(R² + H²)

Surface Area of sloping surface = PI * R * L

Cylinder, base radius R, height H

	Volume	= PI x R² x H / 2
	Area of each end	= PI x R²
	Area of side face	= 2 x PI x R x H
	Total Surface Area	= 2 x PI x R² + 2 x PI x R x H
		= 2 x PI x R x (R + H)
