Answer:

8 pie

Step-by-step explanation:

area of a circle is pie(radius squared)

radius is 4

4 squared is 16

divide by two because its a semi circle

Answer:

8pi

Step-by-step explanation:

A=pi*r^2

A=pi(4^2)

A=16pi

16pi would be the area if the circle was complete, but since this is a semicircle you just have to divide by two which would give us:

A=8pi
