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

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

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

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

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

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

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