Which best describe the base area of the pan
The base area (B) is calculated using:
[tex]B = \pi r^2[/tex]
Where
[tex]r = \frac{1}{2}D[/tex]
So, we have:
[tex]r = \frac{1}{2}*7[/tex]
[tex]r = \frac{7}{2}[/tex]
[tex]r = 3\frac{1}{2}[/tex]
Substitute [tex]r = 3\frac{1}{2}[/tex] in [tex]B = \pi r^2[/tex]
[tex]B = \pi (3\frac{1}{2})^2[/tex]
(a) is correct
