I just watched like 5 vids that were like 20minutes each just for this video under a minute to explain it better than all of them 💀😂

[@bionicwarrior5885]

thats the way its in those ged classes they go on and on about rules to solve a problem that jus confused the hell out of me instead of just showing you how to solve it !

[@Ashakuluwa]

RIGHTTT and i have a test tronmmoroww

[@vijayav7175]

Wow u taught this in under a minute

[@cheeseburger9232]

I want to make a bag 5 foot in diameter, if I roll out the material for the bag how long is the material?

[@DeveloperOfficial]

​@@ultraultralegend9110C=pi×d or C=pi×(r×2) D is diameter which is the radius times 2. Radius is the measurement between the middle of the circle to the edge

This level of Simplicity always helps in quick revisions. Thnaks a lot...........

[@Aud_2011]

My mom teachers and EVERYONE tried to make me understand this but u made me understand this within only 58 seconds totally mind blowing🤯

[@GOAT--7]

thaaaank you i understand tomorrow is the exam! its better than the teacher explaining its so simple

[@tucko11]

Teachers tend to drink way too much caffeine over explain subjects on a particular subject and not just give you the basic details instead and basic concept . People who talk to much are the worst communicators. These teachers are sometimes narcissistic and selfish and like to hear themselves talk . It’s like dude just give me the concise details and or number to the equation that’s it . I have add cuz people are boring asf and think that talking solves everything lol just show me and I can get it within one to two tries and if not I’ll practice when I get home . But if I miss it entirely, that’s not my fault. It’s the teachers fault

[@ashleympoy]

Thank uuuu so much it really helped

[@SylnadiaAuguste-nz4fk]

Thanks this really help me understand

[@Dazu.U]

For these who don't understand: Basically when it's a radii it should be π So first step U should do is write C=2 x r x π So when Ur done instead of π U should write 3.14 So U can't just write C=2 x r x π U should times another number too for example when the radii is 18 cm U should write C=2 x r x 3.14 x 18= First times 18 by 2 so it's 36 then times it with 3.14 so it's now 113.04 there we go! 113.04 cm is the answer

[@luvely_liv]
