Answer: ![1,475.8mm^{2}](https://tex.z-dn.net/?f=1%2C475.8mm%5E%7B2%7D)
Step-by-step explanation:
1. If you join the top part and the bottom part of the figure, you obtain a sphere. Then, you must apply the formula for calculate the surface area of a sphere:
![SA_s=4r^{2}(3.14)](https://tex.z-dn.net/?f=SA_s%3D4r%5E%7B2%7D%283.14%29)
Where r is the radius (
)
2. Then:
![SA_s=4(5mm)^{2}(3.14)=314mm^{2}](https://tex.z-dn.net/?f=SA_s%3D4%285mm%29%5E%7B2%7D%283.14%29%3D314mm%5E%7B2%7D)
3. The formula for calculate the suface area of the red part, which is a cylinder, is:
![SA_c=2(3.14)(r)(h)](https://tex.z-dn.net/?f=SA_c%3D2%283.14%29%28r%29%28h%29)
Where h is the height (h=32mm)
4. Then:
![SA_c=2(3.14)(5mm)(32mm)=1,004.8mm^{2}](https://tex.z-dn.net/?f=SA_c%3D2%283.14%29%285mm%29%2832mm%29%3D1%2C004.8mm%5E%7B2%7D)
5. So, the total surface area is:
![SA_t=314mm^{2}+1,004.8mm^{2}=1,318.8mm^{2}](https://tex.z-dn.net/?f=SA_t%3D314mm%5E%7B2%7D%2B1%2C004.8mm%5E%7B2%7D%3D1%2C318.8mm%5E%7B2%7D)
