In reference to spheres
A = πr squared
the area of a square of a shpere equals 4π times the square of the radius
in reference to spheres
V = 4/3 π r qubed
the volume of a sphere equals 4/3 π times the cube of the radius
in reference to cylinders
L.A. = 2*π*r*height
the lateral area of a cylandar equals the circumference of a base times the height of the cylindar
In reference of a cylinder
V = [π*r squared]*height
the volume of a cylinder equals the area of a base time the height of the cylinder
in reference to a regular pyramid, the L.A. = 1/2 p*h
the lateral area of a regular pyramid equals half the perimeter of the base time the slant height
in reference to pyramids
V = 1/3 B*H
the volume of a pyramid equals the one third the area of the base times the height of the pyramid
in reference to a right prism the L.A. = perimiter*height
the lateral area of a right prism equals the perimiter of a base time the height of the prism
in reference to a right prism V = base area*height
the volume of a right prism equals the area of a base time the height of the prism
