The height of the cone 4 inches.
Step-by-step explanation:
Given,
Volume of cylinder and cone is same.
For cylinder
Radius (r) = 2 inches
Height (h) = 3 inches
For cone
Radius (r) = 3 inches
To find the height of cone say H
Formula:
Volume of cylinder = π
Volume of cone = π
According to the problem,
π = π
or, H =
or, H = 4
Hence,
The height of the cone 4 inches.
