In a corner of the warehouse, there is a pile of corn, which is 1 / 4 cone-shaped. The arc length of the bottom is known to be 4 meters, the height of the cone is 1.5 meters, and the volume is cubic meters

From the corner of the warehouse, we know that the center angle of the bottom arc is 90 degrees
According to the arc length formula, the radius r = 4 / (π / 2) = 8 / π
Then volume = π × (8 / π) ^ 2 × 1.5 = 96 / π cubic meter
