Answer
100.57 square units
Step-by-step explanation
The area of a circle is given as
Area = πr²
The area of a semi-circle is half of the area of a circle.
Area of a semi-circle = ½ (πr²)
r = radius = 8 units
Area of a semi-circle = ½ (πr²)
= ½ [π (8²)]
= ½ (64π)
= 32π
= 100.57 square units
Hope this Helps!!!
