Answer 2

(6π + 12 )cm

Explanation:

The perimeter (circumference) of a semicircle can be calculated using the formula:

Circumference = π × Radius + Diameter

Given that the diameter is 12 cm, the radius (half of the diameter) is 6 cm.

Now, Substitute these values into the formula:

Circumference = π × 6 cm + 12 cm

Circumference = (6π + 12 )cm in terms of pi.

So, the perimeter of the semicircle with a diameter of 12 cm is (6π + 12) cm
