"Forever" 是由 Chris Brown 演唱的一首歌曲,歌詞全文如下:
Verse 1:
We been through the pain,
Been through the struggles,
I ain't ever comin' back to you
Now we both feel like forever
Chorus:
Forever together
Baby forever
This thing that we have,
We ain't never breaking up
Forever together
I will always be,
The only one that you got, girl
Verse 2:
Baby it was real,
We never used to let no one tell us what to do
But now we're forever,
No looking back, we're running with our heads up
Chorus:
Forever together
Baby forever
This thing that we have,
We ain't never breaking up
Forever together
I will always be,
The only one that you got, girl
Bridge:
When we fight, we ain't talking,
Just taking it out in the streets or online
But now we forever,
I'm putting my trust in you girl and you know I'm forever yours
Chorus:
Forever together
Baby forever
This thing that we have,
We ain't never breaking up
Forever together
I will always be,
The only one that you got, girl
Outro:
Forever together, forever這是數學問題:一個圓柱形容器高為6米,底面半徑為2米,容器內裝滿了水。如果將容器倒過來放置,那么水的體積會減少多少?
根據題目,圓柱形容器的高為6米,底面半徑為2米,因此它的體積可以通過底面積乘以高來計算。容器內裝滿了水,所以水的體積就是容器的體積。當容器倒過來放置時,水的體積會減少,減少的體積等於水的體積。由於水的體積等於底面積乘以高的一半,因此減少的體積可以通過將原來的體積除以2來得到。
圓柱形容器的體積為:$3.14 \times 2^{2} \times 6 = 75.36$立方米。當容器倒過來放置時,水的體積會減少一半,所以減少的體積為:$75.36 \div 2 = 37.68$立方米。所以,水的體積會減少37.68立方米。
