Answer: 14.14 ft²
Step-by-step explanation: To calculate the area of a semicircle, use this formula:
[tex]A=\pi r^2/2[/tex]
The radius for this circle is 3 because the diameter of this desk is 6. The radius is half of the diameter. Now, use the formula with the radius.
[tex]A=\pi (3)^2/2[/tex]
[tex]A=14.1372[/tex]
The question asks you to round to the nearest hundredth place, so the final answer you get is 14.14 ft².
Hope this helped! ;)
