A cylindrical glass with a radius of 2 inches and a height of 3 inches is filled completely with water. If all of the water is then poured into a cylindrical glass with a radius of 3, how high is the water in the glass? Use 3.14 for π and round your answer to the nearest hundredth of an inch.

Final answer:

The height of the water in the second glass is approximately 1.41 inches.

Step-by-step explanation:

To find the height of the water in the second glass, we need to calculate the volume of water in the first glass and then use that volume to find the height in the second glass.

Step 1: Calculate the volume of water in the first glass using the formula V = πr²h, where r is the radius and h is the height.

Volume of water in first glass = 3.14 × (2 inches)² × 3 inches = 37.68 cubic inches

Step 2: Use the volume of water in the first glass to calculate the height of the water in the second glass.

The volume of water in the second glass is equal to the volume of water in the first glass, so we can use the formula V = πr²h again.

37.68 cubic inches = 3.14 × (3 inches)² × h

h = 37.68 cubic inches / (3.14 × (3 inches)²) ≈ 1.41 inches

Therefore, the height of the water in the second glass is approximately 1.41 inches.
