Answer:
2814.87
Step-by-step explanation:
Formula = π * r (squared) * height
Radius = 8cm
Height = 14cm
Answer = π*64*14, or 2814.87 (to the nearest hundredth)
what happen do you what to tlak
Answer:
![y=-67.5[cos(\frac{\pi}{15}t)-1]](https://tex.z-dn.net/?f=y%3D-67.5%5Bcos%28%5Cfrac%7B%5Cpi%7D%7B15%7Dt%29-1%5D)
Step-by-step explanation:
We can start solving this problem by doing a drawing of London Eye. (See attached picture).
From the picture, we can see that the tourists will start at the lowest point of the trajectory, which means we can make use of a -cos function. So the function will have the following shape:

where:
A=amplitude
= angular speed.
t= time (in minutes)
b= vertical shift.
In this case:
A= radius = 67.5 m

where the frequency is the number of revolutions it takes every minute, in this case:

so:


and
b= radius, so
b=A
b=67.5m
so we can now build our equation:

which can be factored to:
![y=-67.5[cos(\frac{\pi}{15}t)-1]](https://tex.z-dn.net/?f=y%3D-67.5%5Bcos%28%5Cfrac%7B%5Cpi%7D%7B15%7Dt%29-1%5D)
You can see a graph of what the function looks like in the end on the attached picture.
Solve for x by simplifying both sides of the equation, than isolating the variable.
x ≤ 8/3 or x ≥ 8
