Answer:
2πr³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ← r is the radius and h the height
Here h = 2r, hence
V = πr² × 2r = 2πr³

Answer:
4
Step-by-step explanation:
Coefficient is the number next to the variable, making it 4.
X + 2y = -8
Subtract 'x' to both sides:
2y = -x - 8
DIvide 2 to both sides:
y = -1/2x - 4
Slope is -1/2, not 1.
