Note that where you see the word "Pie" you should replace it with its symbol
First find the area of the circle
Area of circle = Pie × Radius²
Area of circle = Pie × 5²
Area of circle = Pie × 25
Area of circle = 78.54ft²
Now multiply the area by the height to find the volume
78.54 × 11 = 863.94ft³
We can approximate this answer to 864ft³
