A table with a round top is cut in half so that it can be used against a wall. After it is cut, the edge along the wall is 6 \text{ feet}6 feet6, start text, space, f, e, e, t, end text.

The area of a normal circle is  

π

r

2

, but since this is half of a circle, we will divide that by  

2

:

π

r

2

2

=

area of a semicircle

r = radius

The length of the diameter is  

6

, but we will divide that in half to find the radius, since that is what is needed in the equation:

6

2

=

3

Now substitute into the equation:

π

r

2

2

=

area of a semicircle

π

(

3

→

So the area of the tabletop is  

14.14
