Answer:

646.0 cm^3

Step-by-step explanation:

The volume of this cube with side length 8 cm is (8 cm)^3, or 512 cm^3.

The volume of the hemisphere (half sphere) is

V = (1/2)(4/3)(pi)(4 cm)^3                     (since half of the diameter, 8 cm,

V = (2/3)(3.14)(64 cm^3), or                   is the radius)

V = 133.86 cm^3, or approximately 133.9 cm^3.

The volume of the entire solid is (512 + 133.9) cm^3, or 646.0 cm^3

pickupchik [31]

Answer:

D.  conducting regular customer feedback sessions

Step-by-step explanation:

X divided by 4 equals 12 what does x represent to get 12?
sertanlavr [38]
Let's write an equation first:

x divided by 4 can be represented as x/4 

So, x/4 = 12

Now to isolate x, multiply by 4 to cancel the four out. If you do this to one side, you have to do it to the other.

(x/4)4 = 12(4)

so that leaves us with x = 48

In order to get 12 as an answer, x would have to represent 48.
 Hope this helps!
