Find the volume of the bottom and top separately and then add them.
Cylinder volume is the area of the bottom times the height
(22/7)(5^2)•175=13750 ft^3
The volume of a sphere is
V=(4/3)(22/7)r^3
where r is the radius. Here that's also 5 since it fits on the cylinder.
Also we only want half the sphere so use
V=(2/3)(22/7)•5^3=261.9 ft^3
Which we round upto 262.
Now add the parts together
13750+262=14,012 ft^3

➷ Earth's gravity is approximately 9.81
weight = mass x gravity
weight = 4.6 x 9.81
weight = 45.126

Explanation:
From the exercise we know two information. The real speed and the experimental measured by the speedometer
![v_{r}=10km/h=2.77m/s](https://tex.z-dn.net/?f=v_%7Br%7D%3D10km%2Fh%3D2.77m%2Fs)
Since the speedometer is only accurate to within 0.1km/h the experimental speed is
![v_{e}=10km/h-0.1km/h=9.9km/h=2.75m/s](https://tex.z-dn.net/?f=v_%7Be%7D%3D10km%2Fh-0.1km%2Fh%3D9.9km%2Fh%3D2.75m%2Fs)
Knowing that we can calculate Kinetic energy for the real and experimental speed
![E_{r}=\frac{1}{2}mv^2=\frac{1}{2}(61000g)(2.77m/s)^2=234023J](https://tex.z-dn.net/?f=E_%7Br%7D%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2%3D%5Cfrac%7B1%7D%7B2%7D%2861000g%29%282.77m%2Fs%29%5E2%3D234023J)
![E_{e}=\frac{1}{2}mv^2=\frac{1}{2}(61000g)(2.75m/s)^2=230656J](https://tex.z-dn.net/?f=E_%7Be%7D%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2%3D%5Cfrac%7B1%7D%7B2%7D%2861000g%29%282.75m%2Fs%29%5E2%3D230656J)
Now, the potential error in her calculated kinetic energy is:
![e=E_{r}-E_{e}=(234023-230656)J=3367.2J](https://tex.z-dn.net/?f=e%3DE_%7Br%7D-E_%7Be%7D%3D%28234023-230656%29J%3D3367.2J)

I think the correct answer from the choices listed above is option A. The rent is an<span> example of a monthly fixed cost for a sandwich shop. It is a fixed cost since you are required to pay for it per month. Hope this answers the question. Have a nice day.</span>
