Answer: 14.14 ft²
Step-by-step explanation: To calculate the area of a semicircle, use this formula:
![A=\pi r^2/2](https://img.qammunity.org/2022/formulas/mathematics/middle-school/ey7zg18hzd55p8k9w3is68gpmr63vr3uoq.png)
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.
![A=\pi (3)^2/2](https://img.qammunity.org/2022/formulas/mathematics/middle-school/kalknmdxeouzyygp94ux3cxl7dla6otnul.png)
![A=14.1372](https://img.qammunity.org/2022/formulas/mathematics/middle-school/xj9e8u12wh5r2wq6qsfw0l54dbblz1o0s1.png)
The question asks you to round to the nearest hundredth place, so the final answer you get is 14.14 ft².
Hope this helped! ;)
