Answer:
![B = \pi (3\frac{1}{2})^2](https://tex.z-dn.net/?f=B%20%3D%20%5Cpi%20%283%5Cfrac%7B1%7D%7B2%7D%29%5E2)
Step-by-step explanation:
Given
![D = 7\ in](https://tex.z-dn.net/?f=D%20%3D%207%5C%20in)
![H = 2\frac{3}{4}\ in](https://tex.z-dn.net/?f=H%20%3D%202%5Cfrac%7B3%7D%7B4%7D%5C%20in)

Which best describe the base area of the pan
The base area (B) is calculated using:
![B = \pi r^2](https://tex.z-dn.net/?f=B%20%3D%20%5Cpi%20r%5E2)
Where
![r = \frac{1}{2}D](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7DD)
So, we have:
![r = \frac{1}{2}*7](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A7)
![r = \frac{7}{2}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B7%7D%7B2%7D)
![r = 3\frac{1}{2}](https://tex.z-dn.net/?f=r%20%3D%203%5Cfrac%7B1%7D%7B2%7D)
Substitute
in ![B = \pi r^2](https://tex.z-dn.net/?f=B%20%3D%20%5Cpi%20r%5E2)
![B = \pi (3\frac{1}{2})^2](https://tex.z-dn.net/?f=B%20%3D%20%5Cpi%20%283%5Cfrac%7B1%7D%7B2%7D%29%5E2)
