Find the equation of the circumference of a wheel if the radius is 2.5. A. C=3.14⋅2.5⋅2.5

B. C=2+3.14+2.5

C. C=3.14+2.5+2.5

D. C=2⋅3.14⋅2.5

it is d

Step-by-step explanation:

(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
