The fact that I couldn’t understand this topic for a full two weeks in class, and the minute I click on this video I understand everything in less than 11 minutes, says a lot about the education system.😢 Thank you Kevin. ( new subscriber)
Why do we have to add the 20 in the circumference calculation because to get the circumference of a full circle you only use the 2πr formula but since it's a semi circle you multiply by a half
He edits his videos😭😭so much commitment
love this man😢❤

Can I ask why he added the diameter on the semicircle calculation ,but he didn't add it on the previous calculations on the circles
Thank you sir ❤😊
Anyone. Cant i just do the normal calculation for a full circle and just divide the final answer by 2??
Yes because if you ×30 instead 15 it gives an answer of 188,52 then if u divide by 2 you get 94,2
This helps
why do we add 20
20 is the diameter 😅😅
Sir the answer for the last question for perimeter is no 71,4cm it’s 55,71cm
Not it's 41,4
I got the same answer I think he mistakenly used 20 instead of 10,but I just got 55.7
please come to st Dominics in Boksburg
My uncle is a physical science teacher there...
