Take note that the problem has the statement "the distance around the lens" since lens are usually circular, then the question is finding the PERIMETER of the lens.


Given: 

               - the lens is a circle                       (we will use 3.1416 as the pi)

               - the diameter of the lens is 102 cm

Required:

              - the distance around the lens or the perimeter of the lens

Operation:

                  Multiplication

Mathematical Sentence:

                Perimeter of circle = dπ = 102 cm (3.1416)

Solution:

                         102 cm (3.1416)

                    = 320 . 44 cm (rounded to 2 decimal places

Answer: The distance around the lens is 320.44 cm rounded to 2 decimal places.
