Step-by-step explanation:
Area of circle:

By using the area of a circle, we can get the area of a semicircle:

Let's convert the mixed fraction to an improper fraction and then a decimal:
=
= 
Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

Now we have the radius, so we can plug in our values and find the area:


Answer: See the diagram below
=================================================
Explanation:
The base is always perpendicular to the height, meaning the two form a 90 degree angle (aka right angle).
In column 1, refer to the figures as 1, 2 and 3 (working top to bottom).
In column 2, refer to the figures as A, B, C
Figure 1 matches with figure B
Figure 2 matches with figure C
Figure 3 matches with figure A.
These matches are of course the base with the proper height.
