tell 4 answer formula also please​

Answer 1

Answer:

If you want the formula for (v) then herw it is:

Actually its not a long complicated formula but a simple one....if you want to find the circumfrence of a circle,you have to put the formula :

$2\pi \: r \: \: \: \: \: here \: r \: stands \: for \: radius \: of \: the \: circle$

Remember value of π is 3.14 approximately. There is acctually no exact valur of π is founded till now..

Let's silve the question

we are given with:

Radius of circle=7cm

Circumfrence=2πr = 2×π×r

= 2×3.14×7

=44cm

You can also take the value of pi(π) as 22/7

Hence,value of π is 3.14 or 22/7 as given in the question. If there is no value given for pi in the question,you can use any of the value mentioned above.

Thanks,please mark as brainliest if this helped you:)
