Question

The total surface area of a cylinder = 2πrh+πr2


  1. True

  2. False


Solution

The correct option is B

False


A cylinder has 2 circular faces – one at the top and other at the bottom.
Therefore, total surface area = Curved surface area + sum of areas of 2 circular faces
=2πrh+2πr2
=2πr(h+r)
