一个半圆里有一个高为3厘米的三角形求阴影部分的面积
假设阴影部分是指三角形外、半圆之内的部分,那么:
阴影部分的面积=半圆的面积-三角形的面积
假设半圆的半径是r,且三角形的底边是直径,则:
阴影部分的面积=[(πr^2)/2]-2r×3/2
=[(πr^2)/2]-3r

A man's angry voice answered, "You're lying.男人生气的声音回答,"你在撒谎.
You said that last time. We're going to kill you."上次你也是这么说的.我们会杀了你."
When he heard these words, Jim panicked and当他听到这些话,吉姆惊慌失措

I also felt very curious, so I put my head round我也感到很好奇,于是我把我的头来

【约3:16】 神爱世人,甚至将他的独生子赐给他们,叫一切信他的,不至灭亡,反得永生.这段经文当中的"世人"应该是指着什么而言的?
"世人",原文作"世界"Kosmos,英译 For God so loved the world.
神创造了宇宙万物,在亿万个星球中,他竟爱上了地球.地球有什么值得他爱呢?地球是个很小的星球,它既不是太阳系的中心,也不是这个银河系的中心,更不是宇宙的中心,为什么神这样"阿加怕奥"世界呢?圣经叫我们不要爱世界,为什么神自己又要爱世界呢?原来神叫我们不要爱世界的假乐、更不要爱世界的罪恶,而神爱世界,主要是因为世界有照着神形象样式造的人.我们爱世界是"贪爱"世界,但神是这样"阿加怕奥"世界上的人.我们爱世界是要"得"世界,而神爱世界是要"给"独生子来救人.这是"阿加怕奥"的爱.
以色列一直是神所拣选的选民.耶稣出来传道时是对以色列人的:"耶稣说;'我奉差遣,不过是到以色列家迷失的羊那里去.'"(太15:24) 耶稣差遣十二个门徒先传福音,也是"宁可往以色列家迷失的羊那里去"(太10:6).
神最先爱以色列民,这是尼哥底母清楚知道的.但是,耶稣被钉、死而复活,不只为以色列人,更是扩张到全球——神爱"世人",这是尼哥底母无法了解的新道.符类福音,特别是马太福音是对犹太人说的,但约翰福音就普及全世界了,约翰3章16节,不是"神爱以色列",而是神爱"世人",叫凡信他的都得永生.这是对全人类的福音.
