The respective lengths of pencils I and II are

A lead pencil consists of a cylinder of wood with a solid cylinder of graphite filled in the interior.The diameter of the pencil is 7mm and the diameter of the graphite is 1mm. If the length of the pencil is 14cm, find the volume of the wood and that of the graphite.

The length of a pencil is 16 cm and its diameter is 6 mm. What is the ratio of the diameter of the pencil to that of its length?

1/4 of the length of a pencil is black, half of the rest is blue and the remaining part is white. If the pencil is 24cm long, find the length of the white part of the pencil

A lead pencil consists of cylinder of wood with a solid cylinder of graphite fitted into it. The diameter of the pencil is 7 mm. the diameter of the graphite is 1 mm and the length of the pencil is 10 cm. Calculate the weight of the whole pencil in grams correct to three places of decimals if the specific gravity of the the wood is 0.6 and of the graphite 2.3.

While measuring the length of a sharpened pencil, reading of the scale at one end is 2.0 cm and at the other end is 12.1 cm. What is the length of the pencil?

A led pencil consists of a cylinder of wood with a solid cylinder of graphite filled into it. The diameter of pencil is 7mm, the diameter of graphite is 1 mm and the length of the pencil is 10cm. Calculate the weight of the whole pencil, if the specific gravity of the wood is 0.7 (gm)/(cm)^3 and that of graphite is 2.1 (gm)/ (cm)^3
