The second one it's double.
Answer:
2261,9 cm³
Step-by-step explanation:
First, you need to find the area of the base:

A=36
cm²
Now let's multiply it for the height:
36π cm² × 20 cm = 720π cm³
= 2261,9 cm³
Answer:
V=a^3
V=8 1/2^3
V=614.125
Step-by-step explanation:
We don't really have to put this in slope intercept form; it would clearly end up as
y = -4x + something
so we know the slope is -4.
Answer: C) -4
