Acircle has a circumference of 20. it has an arc length of 4, what is the central angle of the arc in degrees?

Step-by-step explanation:

To find the length of an arc,

Angle/360 * circumference

Length = 4

Angle = ?

circumference = 20

Angle/360 * 20 = 4

Rearrange to find the Angle.

Angle/360 = 4 / 20 = 0.2

Angle = 360 * 0.2

(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

i'm not entirely sure
