Answer 1

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

Answer 2

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

Answer 3

I honestly don't know what you just said

Answer 4

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

Answer 5

sorry

Answer 6

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

Answer 7

is the radius 19.90 cm?

Answer 8

Yes. :)

Answer 9

yesss :D

Answer 10

thanks :)
