Answer:
Volume of the cone in ascending order.

cone with DIAMETER of 18 & height of 10
cone with RADIUS of 10 & height of 9
cone with RADIUS of 11 & height of 9
cone with DIAMETER of 20 & height of 12
Step-by-step explanation:
Let
be the volume of the cone.
Let d, r and h be the diameter, radius and height of the cone.
Given:




Arrange the cones in order from lease volume to greatest volume.
Solution:
The volume of the cone is given below.
----------------(1)
where: r is radius of the base of cone.
and h is height of the cone.
The volume of the cone for 






Similarly, for volume of the cone for 







Similarly, for volume of the cone for 





Similarly, for volume of the cone for 





So, the volume of the cone in ascending order.
