[00:00:00]Hi friends.

[00:00:11]for CGceptam.

[00:00:47]area. Sector Start circle. Circle.

[00:01:39]diameter halfime 2 pi r 3.1415 approximately approximately or 22 by 7 33.1 examiner mention if not mention you take Y square content.

[00:02:58]Circle area.

[00:03:14]Max 3.1 circle.

[00:03:49]Let's say square multip Inial ratio 744 radius area 2 equal 3.14 square. Same thing.
