Answer:
2.4 m
Step-by-step explanation:
Given : Height of cylinder = 1.8 m
Diameter of cylinder = 2 m
Diameter of cone = 3 m
To Find: height of the cone
Solution :
Diameter of cylinder = 2 m
Radius = diameter/2 = 2/2 = 1 m
Volume of cylinder =
=
Diameter of cone = 3 m
Radius of cone = diameter/2 = 3/2 =1.5
Volume of cone =
=
Since the cylinder is recast into cone by melting it .So volume will remain same
Hence the height of cone is 2.4 m
