I'm not sure if any source is credible can I get help?

Area = 2908 square meters
Volume= 10540 cubic meters
Explanation
Step 1
Let
heigth=55.86 metres
Diameter=15,484 meters
Step 2
the surface area of the tower
the area= the area of the circle+area of the rectangle.
Step 3
Let
height=55.86 metres
diameter=15.5 meteres
Area= A
Volume= V
heigth= h
[tex]\begin{gathered} \text{A}=\text{area circle+area reactangle} \\ \text{A}=\frac{\pi\cdot diameter^2}{4}+\text{h}\cdot\pi\cdot\text{d} \\ \text{A}=\frac{\pi\cdot(15.5)^2}{4}+\text{55.86}\cdot\pi\cdot\text{1}5.5 \\ \text{A}=188.69+2750.08 \\ \text{A}=2908.77\text{ square meters} \end{gathered}[/tex]Step 4
Volume
the volume of a cylinder is given by:
[tex]\begin{gathered} \text{V}=a_{circle}\cdot h \\ \text{V}=\pi(\frac{d^2}{4})\cdot\text{h} \\ V=\pi\frac{15.5^2}{4}\cdot55.86 \\ V=188.69\cdot55.86 \\ Volume=\text{ 10540 cubic meters} \\ \end{gathered}[/tex]I hope this helps you
