 The height of the cone is 8.6 cm.

Step-by-step explanation:

We know that the volume of cone is given by :-

, where r= radius and h is height

Given : Volume of cone = 225 cm³

Base length = 10 cm

i.e. radius =  [cone has circular base]

Substitute these values in formula , we get

Hence, the height of the cone is 8.6 cm.
