Answer:
the volume of the cylindrical construction pipe is approximately 1490.74 cubic feet.
Step-by-step explanation:
To find the volume of a cylindrical construction pipe, we can use the formula V = πr^2h, where V is the volume, r is the radius, and h is the height or length of the pipe.
In this case, the radius of the pipe is given as 3.5ft, and the length of the pipe is given as 38ft.
Let's substitute these values into the formula:
V = π * (3.5ft)^2 * 38ft
To calculate the volume, we need to square the radius and then multiply it by the length of the pipe, and finally multiply by π (pi), which is approximately 3.14159.
V = 3.14159 * (3.5ft)^2 * 38ft
Simplifying the equation further:
V = 3.14159 * 12.25ft^2 * 38ft
Now, we can calculate the volume:
V = 3.14159 * 12.25ft^2 * 38ft
V ≈ 3.14159 * 474.25ft^3
V ≈ 1490.74ft^3
Therefore, the volume of the cylindrical construction pipe is approximately 1490.74 cubic feet.
