Question

Identify the volume and surface area of the hemisphere in terms of π. HELP ASAP!!

Answer 1

D

Explanation:

Use the formula for the SA of a hemisphere.

`SA=2\pi r^2`

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.

`V=(2\pi r^3)/(3)`

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.
