Answer:
The answer to your question is r = 2x
Step-by-step explanation:
Volume of a cylinder = V = π r² h
r = radius
h = height = x
Volume = 4x³
Then
r² = 
r² = 
r² = 4x²
r = 2x

Answer:
The radius is 12.
Step-by-step explanation:
You're given the center and a point on the circle. The point and the center both have an x-coordinate of -5, so there is no horizontal distance between them. The distance is only in the vertical direction. The distance from 8 to -4 is 12. Since this is the distance from the center to a point on the circle, this equals the radius.
