Solution-
First 9 letters of alphabet are- A,B,C,D,E,F,G,H,I
Total number of ways of selection of 4 letters from 9 alphabets = 9C4
=9!÷((4!).(9-4)!) = 9!÷(4!×5!) = (9×8×7×6)÷(24) = 126
The number of ways of arranging these 4 numbers = 4! = 24
∴ Total number of possible permutations = 9C4×4! = 126×24 = 3024
∴ option number 2 is correct.

Step-by-step explanation:
We have been given that Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. We are asked to find the circumference of an Oreo.
We know that circumference of circle is equal to
, where r represents radius of circle.
We also know that diameter is 2 times radius.

Upon substituting
, we will get:

Using 3.14 as an estimation for π, we will get:


Therefore, the circumference of an Oreo would be 5.495 inches.
