Iv. Using the formula for the volume of a cylinder V = nr?h, calculate the volume of the drum in cubic centimetres (cm).
V=28.5 X 3.94
= 2550.5
= 2550.5x85
= 216789.5cm²
Convert your answer to the nearest litre.
216.79 litres
The fuel capacity of a transport vehicle is 1900L. How many drums of fuel are required to
fill the transport vehicle's fuel tank?

(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: 180 degrees clockwise
