A sphere was dropped into water in a graduation cylinder as shown in the following diagram. The water level rose to the new level shown. {before: 40mL, after: 65mL}
What is the volume of the sphere?
(1)15mL
(2)25mL
(3)40mL
(4)65mL
(2)?

To find the volume of the sphere, we need to determine the change in volume of the water in the graduated cylinder before and after the sphere was dropped.
First, let's calculate the change in volume of the water:
Change in volume = Volume after - Volume before
= 65 mL - 40 mL
= 25 mL
Since the sphere was dropped into the water, it displaced some volume of water equal to its own volume. Therefore, the volume of the sphere is equal to the change in volume of the water.
So, the volume of the sphere is 25 mL.
Therefore, the correct answer is (2) 25 mL.
