Multiple choice

A hemispherical container with radius 6 cm contains 325 m$l$ of milk. Calculate the volume of milk that is needed to fill the container completely. $(\pi = 3.142)$

  1. $147.45\ ml$
  2. $127.45\ ml$
  3. $137.45\ ml$

  4. None

B Correct answer
Explanation

The volume of a hemisphere is (2/3) * pi * r^3. With r = 6, volume = (2/3) * 3.142 * 216 = 452.448 ml. Subtracting the existing 325 ml gives 127.448 ml, which rounds to 127.45 ml.
