+ độ d�i đuờng sinh
+ mặt xung quanh
* Khối n�n tr�n xoay: l� phần kh�ng gian giới hạn bời một h�nh n�n kể cả h�nh n�n đ�.
* Diện t�ch xung quanh của h�nh n�n tr�n xoay:
S(xq) = nửa t�ch độ d�i đường tr�n đ�y v� đường sinh
* Diện t�ch to�n phần cuả h�nh n�n tr�n xoay
S(tp) = S(xq) + diện t�ch mặt đ�y
* Thể t�ch của khối n�n tr�n xoay:
V = một phần ba diện t�ch mặt đ�y v� chiều cao
