Calculate the volume of a straight circular cone when the radius of its base [[$ r $]] and the height its cone [[$ h $]] are

a) [[$ r = 3.0 $]] cm and [[$ h = 4.0 $]] cm.

Answer: The volume of the straight circular cone is cm[[$ ^3 $]].

b) [[$ r = 13.0 $]] cm and [[$ h = 10.0 $]] cm.

Answer: The volume of a straight circular cone is cm[[$ ^3 $]].

c) [[$ r = 5.5 $]] cm and [[$ h = 8.5 $]] cm.

Answer: The volume of a straight circular cone is cm[[$ ^3 $]].
