Answer:
847.8 cubic units , 942 cubic units , 1139.80 cubic units , 1256 cubic units
Step-by-step explanation:
The volume of cone is given as:

1. radius =

height = 12
So, volume =

= 1256 cubic units
2. radius =

height = 10
So, volume =

= 847.8 cubic units
3. radius = 10
height = 9
So, volume =

= 942 cubic units
4. radius = 11
height = 9
So, volume =

= 1139.80 cubic units
Now arranging these in least volume to greatest volume or ascending order.
847.8 cubic units , 942 cubic units , 1139.80 cubic units , 1256 cubic units
