If youknow the diameter of the circle, then
Circumference = (π) x (Diameter).
If youknow the radius of the circle, then
Circumference = (π/2) x(radius).
If you know the area of the circle, then
Circumference= 2 √ (π A) .

Step-by-step explanation:
I'm not sure how to do it, but I took the quiz and it said this was the correct answer
9880 different possibilities are there in Sally's new combination option second 9880 is correct.
<h3>What is permutation and combination?</h3>
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Total unique numbers consists in a Sally locker = 3
From the digits 0 to 39
Total numbers = 40
Apply combination formula:
= C(40, 3)
= 40!/(3!37!)
= 9880
Thus, 9880 different possibilities are there in Sally's new combination option second 9880 is correct.
