If all three are equal, then yes. =>AD=BD=AC
OR in other words, D is in Center of AC.
The total area = \(\pi \frac{r^2}{2}\)
So area of each should be \(\pi \frac{r^2}{2}\)
(1) AD = 2
Nothing about other two.
Insufficient
(2) BD = 5
Nothing about other two.
Insufficient
Combined
AD \(\neq\) BD.
So areas are different.
Sufficient
