Answer:

31.42 cm (rounded up to two decimal places)

Explanation:

We first find the circumference of the semi-circle segment:

The circumference will be given by;
(1)/(2) × π × D (where D is the diameter)

The diameter is 6 cm so circumference is;

(1)/(2) × π × 6 cm = 9.42 cm (rounded up to two decimal places)

The perimeter of the figure therefore is;

8cm + 6 cm + 8 cm + 9.42 cm = 31.42 cm
