Answer:

The perimeter of the semi-circle will be: 3π + 6cm

Step-by-step explanation:

The formula for the perimeter of a semi circle is given as:

= πr + 2r

where,

π = 3.142

r = radius = 3cm

Therefore, the perimeter will then be:

= πr + 2r

= (3 × π) + (2 × 3)

= 3π + 6

Therefore, the perimeter of the semi-circle will be: 3π + 6cm
