Which of the following formulas would find the lateral area of a right cylinder with height equal to hand ras the radius?
A. LA = 2nr
B. LA = 2 rh
C. LA = 291 + 2 trh
D. LA = 2112

answer: c is correct, a regular pentagon

(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

your answer is b ^w^ hope i

i did it myself and i got 4.2 (b) hope its right
