Answer:
Factor of 64.
Step-by-step explanation:
Volume of cylinder: V = πr²h, where V is the volume, r is the radius and h is the length or height.
Now supposing that we multiply the radius by 8. How does the cylinder volume compare to the original volume?
Original volume: V = πr²h
New volume: V = π(8r)²h = 64πr²h
So the volume increases by a factor of 64.
