 OFFSET 1,2 LINKS K. D. Bajpai, Table of n, a(n) for n = 1..5000 FORMULA a(n) = floor((Pi*n^3)/6)). EXAMPLE a(6)=113 since volume is (Pi*n^3)/6 = Pi*6^3/6 = 113.0973355 and floor(113.0973355) = 113. MAPLE KD := proc() local a; a:= floor(evalf((Pi*n^3)/6)); RETURN (a): end: seq(KD(), n=1..100); CROSSREFS Cf. A019673 (Pi/6). Cf. A066645 (volume with radius n). Cf. A228189 (similar sequence for right circular cone).
