求助OG11一道弱智的数学题,大家不要鄙视我
OG11 - Diagnostic Test- Problem solving
20. A right circular cone is inscribed in a hemisphere so that the base of the cone coincides with the base of the hemisphere. What is the ratio of the height of the cone to the radius of the hemisphere?
答案是1比1.可是我不明白的部分在题干。什么叫做the base of the cone coincides with the base of the hemisphere?圆锥的底是一个圆啊,和半圆有什么关系?求哪位大虾指点一下吧,谢谢!! |
