Answer:
V = 150.72 yd³
Step-by-step explanation:
To find the volume, we will need to use the formula
To find the base, we will need to use the volume of a circle, which is .
If the diameter is 8, the radius is half which is equivalent to 4. Put this into the equation:
A = π4²
A = 16π ≈ 50.24.
Now, use this in the Volume of a Pyramid formula:
V = 1/3 (50.24 ·9)
V = 150.72 yd³
