I don't want the answer yet i want to know how to work it out and solve it

yttrium · Answer

Just apply derivation of formulas.
Using C= 2pir, can you transform the formula for r?

anonymous · Answer

I honestly don't know what you just said

anonymous · Answer

if you could try and like... dumb that down for me.. :/

anonymous · Answer

sorry

yttrium · Answer

C = 2pi r. right?
Therefore, we can derive
r = C/2pi
There, just substitute the values and you can now solve for r. :))
