The Greek letter π is spelled pi in English. On a Windows computer you can hold the Alt key and type 227 on the numeric keypad to get the Greek letter.

Error means the actual value might be as high as 1.02F and 1.02R or as low as 0.98F and 0.98R. πdoes not change, so your error calculation is:
P(upper) = 1.02 x (1.02)^2 = 1.061208 which is rounded to 6%error.
P(lower) = 0.98 x (0.98)^2 = 0.941192 which would also be rounded to 6%error.
