The circumference of a circular region is shown what type of number best describes the diameter of the circle? explain

diameter (d) = 2 · r

Circumference (C) = 2 π · r → C = π · d → d =

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
