Having the shape of half a cylinder, with one flat rectangular side and one curved semicircular side.
From Greek 'hemi-' meaning half and Latin 'cylindrus' meaning cylinder. This geometric term has been used in mathematics and engineering since the 1700s.
A hemicylindrical shape is exactly what you get if you cut a tin can in half lengthwise—it's the perfect form for roof tiles, water gutters, and many engineering applications because of how the curve distributes weight.
