4b :     b + 2(b + 2b)     OR     3b + b

First option : 

b + 2(b + 2b)

Simplify.

b + 2b + 4b

Simplify.

3b + 4b

Simplify.

7b

So, the first option is INCORRECT.

Second option :

3b + b

Simplify.

4b

So, our second option is CORRECT.

3b + b

3b+b because 3+1=4 just add b and replace 1 with b
b is the same as 1
3b is the same as 3

ANSWER FOR BRAINILEST.
Lesechka [4]

Answer:

2713

Step-by-step explanation:

The volume of a cylinder is base * height. That means the whole cylinder's volume is 8^2 * 18 * pi = 1152 pi

The volume of a sphere is (4/3)(pi)(r^3) = (4/3)(pi)(6^3) = 288 pi

Cylinder - Sphere = Shaded Volume

1152pi - 288pi = 864pi

Substitute 3.14 for pi, and you get

864(3.14) = 2712.96, which rounds to 2713
