Unit 10 Cylinder & Cone
Cylinder
Lateral Area= C*h=2πrh
Surface area= the lateral area+the area of 2 bases=2πrh+2πr (squared)
Volume=Area of base*height=πr (squared)h
Cone
The arc length of the sector=The circumference of the base
n=360*r/l
Lateral area
πrl
Surface area
πrl+πr (squared)
在圆柱和圆锥等底等高的情况下，圆柱的体积是圆锥的3倍
一个圆锥有无数条母线
l is slant height, r is the radius of the base
圆柱有无数条高
圆柱的底面是完全相等的两个圆
圆柱的两个底面之间的距离是圆柱的高h
圆锥只有一个底面，底面是个圆，圆锥的侧面是个曲面，把圆锥的侧面展开得到一个扇形
圆锥有一条高
