Let's do this question, Esquire of maximum area is cut out from a circular piece of cardboard of radius
42 centimeter.
All right, so this is a circular piece of cardboard of radius, 42 centimeter pine, the area of the
remaining cardboard.
Now, all of this, you're cutting out the square.
Now you need to find the remaining area.
That's this spot over here.
Can you tell me the answer?
Or here you can see that the diagonal of the square is the diameter of the circle right now.
What is the radius of the circle?
It's 42 centimeter.
So this also is 42 and this is also equal to 42.
Therefore, the diagonal is equal to 42 plus 42.
That is equal to eighty four centimeter.
Right now, if the diagonal is equal to eighty four centimeter, can you tell me the side of the square?
This is the side right now.
It is the side and is the side.
The diagonal is equal to it.
Right diagonal is equal right to it.
Why is that so.
Diagonal is the root of a squared plus is square which is route to it now.
The diagonal is equal to eighty four so Rouper is equal to eighty four centimeter.
And with that you can find a right is equal to eighty four birute two.
Now to find the answer to the question, you need to do the area of the circle minus the area of the
square.
That would be Pyar Square minus a square which is equal to 22 by seven to forty two in the 42 Despierta
Square, minus eighty four by road to the square.
That's eighty four to eighty four by two.
Right now on simplification you will get this as it's to the simplification and you get the answers.
Five five four four minus three, five to eight which is equal to 2016.
And that is your answer.
