Answer:
1. Use this form V = πr²h to obtain around π(4)² * 5 ≈ 251.3 m³
2. Multiply all the lengths of the sides to obtain this volume 42 in³
3. Multiply all the lengths of the sides and divide that by 2 to obtain 154 cm³
Try the rest of the problems by yourself... Remember that:
V = Ah where A is the area of the base.
