in school i learnt that if a number is able to divided by 7 then it could use 22/7 is that correct or no

@joshuajoseph2692 3 месяца назад

@@Hydrationator2 Yes, that is correct. If a number can be divided by 7 without any remainder, then it means the number is divisible by 7. In such cases, you could represent the division as a fraction using to get an approximate value for simplicity or ease of calculation.

@JoseCasillas-xg8yu Год назад

i believe you made a smaller error in finding the area of the first problem which consist of the radium being 3 inches, because if i followed the formula correctly 3 squared equal 9 , then multiplied by 3.14 gives you 28.26 not 28.27.

@Malik-mx8st Год назад

I noticed the same thing I was replaying the video a bunch of times scratching my head trying to figure out how he got 28.27 I got 28.26 and even typed it in the calculator and got the same answer..

@nicolebentley559 Год назад

@@Malik-mx8st I had the same issue, but if you use the pie symbol on your calculator instead of using 3.14 you'll see how we rounded to get 28.27. You may have to switch from a basic calculator mode to scientific if you're using the one on your computer.

@kdub175 Год назад

28.2743 = 3x3x3.14159

@Mykeydedenbach5hundred74 5 месяцев назад

Im getting no 28. Anything out of this and im using a calculator on an iphone. Simplified this problem is…3.14 aka pie, times 3, 3 being the radius multiplied with pie gives you 9.42477796, squaring that to itself makes it 88.8264396, all of the multiples in this number are multiples of pie.

@Mykeydedenbach5hundred74 5 месяцев назад

Thank you Mr. J. This is a big help. One thing I have a question about is, why did you round to the hundreths place ? Is this a rule when finding the area of a circle?

@blondorrainbow9959 Год назад

No it’s just that pi has never ending digits so he just rounds it to the hundredths place

Thank you for the video, actually for all of your videos. I have a question though. Why is the answer to the third circle in cm, not feet when the radius is 4ft? Please clear up this confusion for me.

@ChessPotato49 Год назад

Because they labeled it as cm not in so then it would be for cm instead of in if that makes any sense
