Step-by-step explanation:
Given that, the radius of the base of a cone is 1.5 cm and its height is 5 cm.
To find out: The volume of the cone.
We know that, volume of a cone =31×πr2h
∴ Volume of the given cone =31×722×1.52×5[∵ π=722]
⇒31×722×2.25×5=21247.5
∴ Volume of the cone =11.79 cm3.
Hence, the volume of the given cone is 11.79 cm3.
