Find how many prime numbers appear in the first 100 digits of e and pi

For example, pi:
(1) : 3 ............. prime number
(2) : 31 ........... prime number
(3) : 314 .......... 314 = 2 * 157
(4) : 3141 ......... 3141 = 3^2 * 349
(5) : 31415 ........ 31415 = 5 * 61 * 103
(6) : 314159 ........ prime number
(7) : 3141592 ....... 3141592 = 2^3 * 392699

How many prime numbers can you find?

UPDATE: New puzzle

You are at a lake and have two empty containers capable of holding exactly

pi (=3.141592653589...) and e (= 2.7182818284590....) liters of liquid.

How many transfers of liquid will it take you to get a volume of liquid in one container that is within one percent of exactly one liter?
