Эхлээд цилиндрийн дугуй талбайн хэмжээг олно (тодорхойгүй бол "a" гэж тэмдэглэнэ) . Тэгэхийн тулд цилиндрийн тойргийн уртыг диаметрт хуваана. Хариу 3.14 орчим болно, түүнийг пи (π) гэдэг. Дараа нь диаметрийг (⌀) 2-т хувааж радиусыг (r) олно (r = ⌀ / 2). Ингээд радиусын квадратыг олно (r² = r * r). Радиусын квадратыг пи буюу 3.14-т үржүүлэхэд цилиндрийн дугуй талбайн хэмжээ гарна (a = r² * π).
Цилиндрийн эзлэхүүнийг (V) олохын тулд цилиндрийн дугуй талбайн хэмжээг (a) циллиндрийн өндрийн хэмжээнд (h) үржүүлнэ (V = a * h).
