No. The hepatitis B vaccine series should not berestarted when doses are delayed; rather, the seriesshould be continued from where it left off. Thevaccine recipient should receive the second doseof vaccine now and the third dose 2â5 monthslater.
The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter Ï, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference. In English, Ï is pronounced as pie (/paÉª/, paÉª).
Pi is equal to the circumference of a circle divided by the diameter of that circle. It is a transendental number, meaning that it can not be exactly expressed by any equation with rational coefficients and powers. The best approximation using a two-digit fraction is 22/7.
