設(shè)圓錐形容器的底面半徑為
?$2r，$?高為?$2h，$?則中間的底面
半徑為?$r，$?高為?$h。$?
?$V_{原來(lái)油}=\frac {1}{3}\pi (2r)^2×2h=\frac {8}{3}\pi r^2h$?
?$V_{剩下油}=\frac {1}{3}\pi r^2h$?
?$ \frac {V_{剩下油}}{V_{原來(lái)油}}=\frac {\frac {1}{3}\pi r^2h}{\frac {8}{3}\pi r^2h}=\frac {1}{8}$?
?$2000×(1 - \frac {1}{8})=1750($?克?$)$?
答：香油流失了?$1750$?克。
