To find the volume of an aquarium in cubic feet, you can follow these steps:

1. Convert the height and radius measurements to the same unit. In this case, let's convert them both to inches.
- The height is given as 25 1/2 inches, which can also be represented as 25.5 inches.
- The radius is given as 21 inches.

2. Calculate the volume of the aquarium using the formula for the volume of a cylinder:
- V = π * r^2 * h
- V represents the volume
- π represents the mathematical constant pi (approximately 3.14159)
- r represents the radius of the circular base
- h represents the height

3. Substitute the values into the formula:
- V = 3.14159 * (21 inches)^2 * 25.5 inches

4. Calculate the volume using a calculator:
- V ≈ 33,510.61 cubic inches

5. Convert the volume from cubic inches to cubic feet:
- Since there are 12 inches in a foot, 1 cubic foot is equal to (12 inches)^3.
- Divide the volume in cubic inches by (12 inches)^3 to convert to cubic feet:
- V = 33,510.61 cubic inches / (12 inches)^3

6. Calculate the final volume in cubic feet using a calculator:
- V ≈ 19.36 cubic feet

Therefore, the volume of the aquarium is approximately 19.36 cubic feet.
