UNDING OFF NUMBERS TO CERTAIN DECIMAL PLACES
e rules for rounding off numbers to certain decimal places are as follows:​

(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

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
