Answer:
Q: How much of the cylinder does the sphere fill
A: The sphere fills the whole cylinder
Step-by-step explanation:
The sphere's height, as written in the picture (The red words) says 2r and the same goes for the cylinder, therefore if they both say, "h = 2r" then it is evident that they both are equivalent. Therefore, the Sphere fills up the whole cylinder.
