Answer 2

The surface area of a cylinder whose radius of the base and height are equal to 1 unit is​ 4П square units.

We know that the surface area of a cylinder of radius 'r' and height 'h' is given as:

SA = 2cr² + 2Пrh

= 2Пr(r+h)

It is given that, the radius r = 1 and height also = 1. Replacing these value in the surface area equation, we get,

SA = 2П(1)(1+1)

= 2П(2)

= 4П square units
