???????????????????????????????????????????????

$A_{square} = (\frac{P}{4})^2$ $A_{circle} = \pi*(\frac{P}{2\pi})^2$ looks like the area of the circle is greater

3. anonymous

yeah but by how much

4. anonymous

which option and why

5. anonymous

option B. seems the area of a circle is $\frac{4}{\pi}$times greater than the area of a square

6. anonymous

no u chose option wrong but ure method is right it will be$P ^{2}\div4\pi ^{2}\times \pi so that will be P/4\pi$ so option d

7. anonymous

ok thnx agd see the other question

8. anonymous

how could my option be wrong?

agdgdgdgwngo is right
