1
00:00:00,530 --> 00:00:07,100
Let's do this question, Esquire of maximum area is cut out from a circular piece of cardboard of radius

2
00:00:07,100 --> 00:00:08,300
42 centimeter.

3
00:00:08,600 --> 00:00:14,660
All right, so this is a circular piece of cardboard of radius, 42 centimeter pine, the area of the

4
00:00:14,660 --> 00:00:15,650
remaining cardboard.

5
00:00:15,950 --> 00:00:18,260
Now, all of this, you're cutting out the square.

6
00:00:18,440 --> 00:00:20,570
Now you need to find the remaining area.

7
00:00:20,570 --> 00:00:21,940
That's this spot over here.

8
00:00:22,430 --> 00:00:23,660
Can you tell me the answer?

9
00:00:23,930 --> 00:00:31,010
Or here you can see that the diagonal of the square is the diameter of the circle right now.

10
00:00:31,040 --> 00:00:33,550
What is the radius of the circle?

11
00:00:33,560 --> 00:00:34,820
It's 42 centimeter.

12
00:00:35,000 --> 00:00:38,050
So this also is 42 and this is also equal to 42.

13
00:00:38,270 --> 00:00:41,690
Therefore, the diagonal is equal to 42 plus 42.

14
00:00:41,690 --> 00:00:43,910
That is equal to eighty four centimeter.

15
00:00:44,120 --> 00:00:49,720
Right now, if the diagonal is equal to eighty four centimeter, can you tell me the side of the square?

16
00:00:49,910 --> 00:00:51,520
This is the side right now.

17
00:00:51,530 --> 00:00:53,480
It is the side and is the side.

18
00:00:53,480 --> 00:00:55,330
The diagonal is equal to it.

19
00:00:55,340 --> 00:00:57,590
Right diagonal is equal right to it.

20
00:00:57,620 --> 00:00:58,330
Why is that so.

21
00:00:58,580 --> 00:01:03,650
Diagonal is the root of a squared plus is square which is route to it now.

22
00:01:03,650 --> 00:01:08,490
The diagonal is equal to eighty four so Rouper is equal to eighty four centimeter.

23
00:01:08,780 --> 00:01:13,160
And with that you can find a right is equal to eighty four birute two.

24
00:01:13,460 --> 00:01:20,180
Now to find the answer to the question, you need to do the area of the circle minus the area of the

25
00:01:20,180 --> 00:01:20,630
square.

26
00:01:20,840 --> 00:01:28,490
That would be Pyar Square minus a square which is equal to 22 by seven to forty two in the 42 Despierta

27
00:01:28,490 --> 00:01:32,140
Square, minus eighty four by road to the square.

28
00:01:32,180 --> 00:01:34,010
That's eighty four to eighty four by two.

29
00:01:34,190 --> 00:01:42,050
Right now on simplification you will get this as it's to the simplification and you get the answers.

30
00:01:42,050 --> 00:01:48,140
Five five four four minus three, five to eight which is equal to 2016.

31
00:01:48,260 --> 00:01:49,940
And that is your answer.
