Answer:
Height = 18 units
Explanation:
Given :
Volume= 162pi, radius= 3 units
We know,
Volume of Cylinder= Pi * (radius)^2*h
now you can substitute, (P.S: dont put the value of pi as it will get cancelled)
162 pi = pi* (3)^2* h
162= 9h
∴h= 162/9= 18
∴ height is 18 units.
Hope it helps. But I am not sure if the answer is correct or not.
