Answer: 20cm

Step-by-step explanation:

First, add up the 3 sides you already know.

6+6+3 = 15.

Now you have to find the length of the semi circle which is half the circumference of a circle.

The equation for the circumference is 2πr.

The diameter of the circle is 3 meaning the radius is 1.5.

Plug this into the equation.

2 * π * 1.5 and you get approximately 9.42
Since it is only have a circle, you have to divide this by 2 to get half the circumference.

When you do this, you get 4.71

Add up 15 and 4.71 and you get 19.71 which rounds up to 20.
