Step-by-step explanation:

The diameter of circle is 12 cm

So, Radius will be 6 cm (12/2)

So, As we know circumference of circle is

$2\pi \: r$

So, Assuming the value of π is 22/7

we get

$2 \times \frac{22}{7} \times 6 = 37.71$

So to get the number of invitation

$\frac{180}{37.7} = 4.7$

So, She can made 4 complete invitation.
