Hi, the circled one is what I need help with, thank you :)

The volume of the cone is 26.18 ( round it to the nearest tenth)

The height of the cone is 4

Step-by-step explanation:

Volume: 3.14 x 2.5^2(squared; which means you mst multiply 2.5 x 2.5) x 4 = 26.2(rounded)

Height: 4. It shows it on the diagram of the cone.

Note:

Hope this helps, and let me know if my answer is incorrect, for the other users who will see this message.
