FIND THE VOLUME OF THE CONE!

15.5

Step-by-step explanation:

the r=1.9 h=4.1

A= 38.31 mm^3

Step-by-step explanation:

You take pi times 1.9, which is your radius. Then multiply that quotient by 1.9 plus the square root of 4.1 squared plus 1.9 squared. And you shall get your answer, 38.31 Your Welcome :)

(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

answer: correct
