Consider a distribution with an unknown parameter pi. If the true value of pi is not known but has been estimated, then the estimated value is usually denoted by pi-hat. This is to distinguish between a known parameter and an estimated one.
aryabhatta discovered it as 3.1416. value of i is 22/7
radians = degrees *(pi/180) pi = 3.14159 (approximately) In Excel and other programs, you can use +pi() for pi.
Pi is the population proportion of successes.
Commit to memory A = pi r^2 C = 2 pi r or pi d NB 2r = d This is elementary school maths. Hence if d = 2r 8 , then r = 8/2 = 4 Hence A = pi 4^2 A = 16 pi pi is a constant at 3.141592.... A = 16*3.41592.... = 50.26554.... units^2
