求圆柱体表面积的特例教学谈○四川肖文辉几何图形表面积的计算，其实质是组合图形面积的计算。但是，因各个面都附在一个几何体上，计算所需的数据都要从几何体本身的数据中去找，在解决实际问题时，又得根据具体情况灵活处理，故这是一个难点。义务教育六年制小学数学课... Special case study of cylinder surface area ○ Sichuan Xiao Wenhui geometric surface area calculation, the essence is the combination of graphics area calculation. However, since all surfaces are attached to a geometric body, the data required for the calculation must be found from the data of the geometric body itself. This is a difficult task to solve in practice when it has to be flexibly handled according to specific situations. Compulsory education six-year primary school math class ...
