Question

Suppose the circumference of a circle is
2π

What is its radius?

Answer 1

Formula:

\(\sf C = 2 \pi r\)

Plug in what we know:

\(\sf 2 \pi = 2 \pi r\)

Divide 2 pi to both sides, what's 2 pi / 2 pi?

Answer 2

1 pi ?? @iGreen

Answer 3

Yes, but we no longer have pi.

Answer 4

pi / pi cancels out.l

Answer 5

So we have:

\(\sf r = 1\)

Answer 6

so its just 1 @iGreen

Answer 7

Yep!

Answer 8

THX! @iGreen

Answer 9

Np!
