- 1/5

Step-by-step explanation:

-1/3= -0.333333

1/2= 0.5

-1/5= -0.2

1/4= 0.25

When you compare them, you see that -0.2 is closer to 0. Since -0.2 is equivalent to -1/5, -1/5 is the answer.

(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

use formula for the circle a=3.14
