RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Geometry - Cylinders, Cones & Spheres

Here are formulas for some of the most commonly used cylinders, cones, and spheres, all with symmetry about the axis of rotation. Equations for surface area and circumference are provided.

B₁= area of lower base

B₂= area of upper base

D = diameter

h = altitude

R = radius of base

S = lateral surface

s = slant length,

T = total surface

V = volume
