Answer:
D
Step-by-step explanation:
Use the formula for the SA of a hemisphere.

Now we can find the radius of the hemisphere, which is 15.
Then, we can square that and multiply it by 2 to get 450.
Now, let's use the formula for the Volume of a hemisphere.

Now we can cube 15 and multiply it by 2 to get 6750.
Then we can divide this number by 3.
2250.
So the answer is D.

Sinah = 28 sticks
There are 8 sticks in each pack
g = number of packs of gum that sinah bought?

8g = 40
Divide both sides by 8
g = 40 / 8
g = 5 packs
