Answer:
so, the figure here is a cylinder with a semi sphere on the top, we know the height of whole structure, and the radius of the semi sphere, which is the same as the radius of the cylinder (you can see it because the radius of the semisphere is constant, and you can thin on it as half a sphere over a cylinder).
First, the cylinder will be the structure without the semi sphere, so his height will be te total height minus the radius of the semi sphere, which is 0.9μm.
so now we know the height and the radius of the cylinder, the surface or the sides of it is 2*3.14*r*h = 2*3.14*0.9μm*0.1μm = 0.5662

Answer:
b > 17
Step-by-step explanation:
In this question, you would have to solve the inequality.
Solve for b:
17b - 21 > 12b + 64
Subtract 12b from both sides:
5b - 21 > 64
Add 21 to both sides
5b > 85
Divide both sides by 5:
b > 17
b > 17 will be your answer.
