The number of permutations of the 25 letters taken 2 at a time (with repetitions) is: $25^{2}$
The number of permutations of the 9 digits taken 4 at a time (with repetitions) is:
$9^{4}$
Each permutation of letters can be taken with each permutation of digits, therefore the total number of possible passwords is:
$25^{2}\times 9^{4}=4,100,625$

you have a full cylindrical glass of water that stands 8 inches tall and has a radius of 1.5 inches .if you pour the water into

Romashka-Z-Leto [24]

Volume of cylinder=πr²h volume of another cylinder=πr²h
=22/7×1.5×1.5×8 =22/7×2.5×2.5×12
=396/7 =1560/7
=56.57 =235.71

=235.71-56.57
=179.14 amount of water is able to hold by the larger cylinder
