Step-by-step explanation:
evatulate: −16 (3−7)
-48+112
Answer: 
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:

Where r is the radius (
)
2. Then:

3. The formula for calculate the suface area of the red part, which is a cylinder, is:

Where h is the height (h=32mm)
4. Then:

5. So, the total surface area is:

Answer:
x=63
Step-by-step explanation:
55+62+x=180
117+x=180
180-117=63
x=63
The answer is B.
