The volume of a right circular cone can be calculated using the formula: V = (1/3)πr^2h, where V is the volume, π is pi, r is the radius of the base, and h is the height.
Plugging in the values given:
V = (1/3)π(19.3^2)(18.8)
Calculating:
V ≈ (1/3)π(372.49)(18.8)
V ≈ (1/3)(3.14159)(372.49)(18.8)
V ≈ 20.94348(372.49)(18.8)
V ≈ 20.94348(7005.372)
V ≈ 146,427.9586
Rounding to the nearest tenth of a cubic meter:
V ≈ 146,427.96 cubic meters
Therefore, the volume of the cone is approximately 146,427.96 cubic meters.
