The surface area of a cone can be derived from the surface area of a square pyramid. Start with a square pyramid and just keep increasing the number of sides of the base. After a very large number of sides, you can see that the figure will eventually look like a cone.This is shown ...
题目The total surface area of a cone is equal to ___. A. LSA + BA B. LSA - BA C. LSA×BA D. LSA÷BA 相关知识点: 试题来源: 解析 A。中文解析:圆锥的总面积等于侧面积加上底面积,即 TSA = LSA + BA。反馈 收藏
