Answer:
23.2328
Step-by-step explanation:
The circumference of a circle is π x diameter.
In this case, as the circle is a semi-circle, we need to multiply the perimeter by 2 to get the perimeter of the full circle. (72.988)
After that, to get the diameter alone, we need to divide the full perimeter by π. (72.988/π=23.2328)
The diameter of the semi-circle is 23.2328
