K. D. Bajpai, Table of n, a(n) for n = 1..5000
FORMULA
a(n) = floor(Pi*n^3/2).
EXAMPLE
a(9) = 1145 since volume = ((Pi*n*1.5*n)*(n)/3) = ((Pi*9*1.5*9)*(9)/3) = 1145.110522 and floor(1145.110522) = 1145.
MAPLE
KD := proc() local a; a:= floor(((Pi*n*1.5*n)*(n)/3));
RETURN (a):
end:
seq(KD(), n=1..100);
