Tyler cuts out a cardboard circle with a radius and stacks them to make the shape of a cylinder five centimeters high. What is the approximate volume of the cylinder

Don't get confused with the language of the question. The cylinder was made by stacking cut pieces of cardboard in circular shape. It is also given that the radius of circle is unit (1).

Volume of cylinder = πr²h = 3.14*1²*5 = 15.7 cm³
