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:
its A
Step-by-step explanation:
not gonna explain it cause I dont have to ._. plus it wasnt that hard
They must conform with Pythagoras theorem
It is set 4 because
(sqrt 2)^2 + (sqrt 7)^2 = 3^2
2 + 7 = 9
No that is an inverse variation, a direct variation must have a y that is directly proportional to x while the picture shows a y that is inversely proportional to x <span />
