Final answer:
To calculate the volume of the cylindrical pipe, the diameter is halved to get the radius, and then the volume formula V = πr²h is used, resulting in an approximate volume of 212.38 cubic feet.
Step-by-step explanation:
The volume of a cylinder can be determined using the formula V = πr²h.
To calculate the volume of the cylindrical construction pipe, we convert the diameter to radius by dividing it by 2, so the radius (r) is 1.5 ft. Plugging the values into the formula, we get:
- V = π × (1.5 ft)² × 30 ft
- V = π × 2.25 ft² × 30 ft
- V = π × 67.5 ft³
- V ≈ 3.14159 × 67.5 ft³ ≈ 212.38 ft³
The approximate volume of the pipe is 212.38 cubic feet.
