perimeter of a circle = circumference of the circle

circumference = 2πr

given, radius = x

$\pi = \frac{22}{7}$

circumference =

$2 \times \frac{22}{7} \times x$

circumference =

$\frac{44x}{7}$

= 4πx

Dinosaurs1842: um.. I don't understand hindi..

wwwdcmeher2018: but hear is not given that one

wwwdcmeher2018: ok

wwwdcmeher2018: i havent any answer of this question so i am asking to you sir

Dinosaurs1842: ok my class is gonna start.. I'll give you a detailed explanation after a few minutes

Dinosaurs1842: ok?

wwwdcmeher2018: ok sir bye my online class is also going on

Dinosaurs1842: if you want you can express this as 4πx also

Dinosaurs1842: it's correct both the ways

Dinosaurs1842: fine, if you are getting confused write 4πx. But when sums are given to find the circumference of a circle with radius 'n' cm check what they have given the value of π as. If they haven't given any value then it's understood that you have to take the Value as 22/7
