Answer:
11232000
Step-by-step explanation:
Given that an identification code is to consist of 2 letters followed by 3 digits.
Also given that repetition is not permitted.
Since order matters here we find that permutation to be used.
Out of 26 letters, 2 letters can be selected without repitition in ways
And 3 codes can be selected from 10 digits in ways
Hence total number of codes =
No of ways = 11232000
Part A :
Area = π*r² = π(d/2)² = π*(8/2)² =
π*4² = π*16 square inches
Part B:
d=8+4 = 12 and r = d/2 = 6 inches
We know :
Area = π*r²
Area = π*6²
=36π
