What is the volume (in cubic units) of a cylinder with a height equal to the diameter and a radius is 4 units?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 128π.
The volume of the cylinder = πr2h
Height = Diameter = 2r = 8 units
Volume = π(4)2(8) = 128π cubic units
