Question

Rewrite the equation

C
=
2
πr
to show the expression that can be used to fine the value of r.

Answer 1

r=C/2π

Explanation:

here we just have to rearrange the given formulae in such a way that it finds out the value of r.

Given formulae is C=2πr

we can carry 2π to the left hand side.

r=
`(C)/(2π)` . is the recquired formulae.
