Answer:
B
Step-by-step explanation:
The formula for area of a circle, or the base of a cylinder is π r^2
We can use that to figure out the radius of the circle.
64π=πr^2
Divide both sides by π
64=r^2
r=8
Now, we just have to multiply the base area by the height to find the volume.
The height of the cylinder is 16. (8*2)
V=64π*16
V=1024π
