An ink container of cylindrical shape is filled with ink upto 71%. Ball pen refills of length
12 cm and inner diameter 2 mm are filled upto 84%. If the height and radius of the ink
container are 14 cm and 6 cm respectively, find the number of refills that can be filled with this ink
Answers
Answer:
Step-by-step explanation:
Volume of cylindrical ink container = πr²h
= 22/7 * 6² * 14
= 1584 cm³
Amount of ink filled in the container = 1584 * 71/100
= 1124.64 cm³
Volume of refill = πr²h
= 22/7 * 0.1² * 12 .... (d=2mm ∴ r= 1mm = 0.1cm)
=0.3771cm³
Amount of ink filled in refill = 0.3771*84/100
= 0.3167cm³
No. of refills that can be filled with this ink = capacity of ink pot/capacity of
refill
= 112.64/0.3167
= 355.667 ≈ 356
∴ Approximately 356 refills can be filled with the ink pot
