Step-by-step explanation:

✦ So think of finding a semi-circle like a regular circle. Just Find the Circumference like usual:

  ✦ 2 × π × 5 = 31.41

✦ Now that we've done that all you have to do is divide by 2 since a semi-circle just means half of a regular circle:

  ✦ 31.41 ÷ 2 = 15.707 or If rounded 15.705

✦ You could also use the formula for a semi-circle:

  ✦ ½ × 2 × π × r
