Solution
Length of the pencil = 18 cm
Radius of the pencil = 0.4 cm
The diameter of the pencil is:
Diameter = 2 × Radius = 2 × 0.4 = 0.8 cm.
The ratio of the length to the diameter is:
`"Ratio" = "Length"/"Diameter" = 18/0.8`
`"Ratio" = 180/8 = 22.5`
The ratio of the length to the diameter is: 22.5 : 1
