A cylindrical part with a bottom diameter of 8 decimeters and a height of 6 decimeters is fused into a conical part with a bottom diameter of 12 decimeters. What is the height of the conical part
Volume of cylinder: 3.14 × 4 × 4 × 6 = 301.44 (cubic decimeter)
301.44 × 3 ÷ (3.14 × 6 × 6) = 8 (decimeter) - height of cone
