Thank you so much! I think the reason I’m so bad at math is that I get distracted easily.. I had to watch this 4 times so I could actually listen to you.. 🤭🤭
The perimeter of the sector is the arc length + radius + radius. By the way, the arc length is *theta/360 degrees times the circumference of circle(2TTr) which you will have to put in radiance because the other lengths are NOT in degrees in this problem* So to solve for the sector, theta/360 * 2TT(7) + 7 + 7 AND to solve for the OUTSIDE shape, the length of each side is 28 cm so you add each side or you can just multiply by 4, lol.
This is a ryt answer kk We understand you firstly we have 4 semicircle which equal to 1 circle and given radius is 14cm then area is 196π and we find area of square , we have a 28cm side of square then area of square is 28^2=784 Shaded area is =[784-196π]
Madam I am very sorry,it is not a correct way of teaching, please learn fundamental mathematics some more time because you are a learner but not a teacher of mathematics:- CHVSN as a INDIAN mathematician but till I am a learner of fundamental mathematics
