Answer:
1) V≈923.62824
2) V= 28.27433
1. 923.16 or 294 Pi
2. 3052.08 or 972 Pi
Step-by-step explanation:
Formula for volume of a cone = Pi r^2 h/3
If diameter is 14, radius is 7
Pi 7^2 18/3
Pi 49 6
Pi 294
923.16
Formula for volume of a sphere = 4/3 pi r^3
If diameter is 18, radius is 9
4/3 pi 9^3
4/3 pi 729
972 pi
3052.08
