Origin:
1940-45; so called because first found in the blood of RHesus monkeys
any of a type of specific antigen present on the surface of red blood cells, persons having inherited such antigens being designated Rh+ (Rh positive) and persons lacking them, a much smaller group, being designated Rh− (Rh negative):blood of Rh− persons is incompatible with Rh+ blood because of antibody reaction, and an Rh− woman who bears an Rh+ baby will have formed antibodies to the fetal blood that, unless removed from her bloodstream by apheresis in a subsequent pregnancy, will be carried across the placenta and destroy red blood cells of the next Rh+ fetus, resulting in erythroblastosis in the newborn.

H would have stood for Henry but R stood for Rex which is Latin for King.
H stands for Hurtzsprung and the R stands for Russell

H C P may stand for "highest common factor" in mathematics, or "hexagonal close-packed" in the context of crystal structures.
Volume = area circular end × height = πR²H units³ Surface area = 2 × area of circular end + area of curved side = 2πR² + 2πRH units² = 2πR(R + H) units² If lengths are changed by a scale factor of n, areas are changed by a scale factor of n² and volumes are changed by a scale factor of n³. If the dimensions are tripled, the new volume is 3³πR²H units³ = 27πR²H units³ The new surface area is 3²×2πR(R + H) units² = 18πR(R + H) units²
Haters means... H- Having A- Anger T- Towards E- Everyone R- Reaching S- Success
Surface Area of Sphere = 4*Pi*r2 Surface Area of Cylinder = 2*Pi*r2+2*Pi*r*h If we set them as equal: 4*Pi*r2 = 2*Pi*r2+2*Pi*r*h ' Factor out 2*Pi*r 4*Pi*r2 = 2*Pi*r*(r+h) ' Divide both sides by 2*Pi*r 2*r=r+h ' Subtract r from both sides r=h Diameter = 2*r so h=d/2 In this case, d=16m h=8m
