Semicircle in a square

Find the area of a largest semicircle in a unit square?

The largest possible radius is 0.5

Hence largest possible semicircle will have area
= pi*r^2

= 3.142*1/4

= 0.7855 (or in other words pi/4)

Cheers!

but if the problem was that too simple I wudnt hve asked dat...radius is greater than .5 !!

it is largest semicircle and not circle.

so radius can be one

Its largest semicircle!!!!!!! :mad:

No part of semicircle shud go out of square
And the radius of largest semicircle is not .5!!!
Think more!!!

Initially i want formula for calculating semicircle area.
I checked in a google and i got your question and answer.
Now tell me once you know the answer then how you work out your own way?
