Q144 (IAS/1999) Science & Technology › Basic Science (Physics, Chemistry, Biology) › Quantitative aptitude topics Answer Verified

A hemispherical bowl is filled to the brim with a beverage. The contents of a bowl are transferred into a cylindrical vessel whose radius is 50% more than its height. If the diameter is same for both bowl and cylinder, then the volume of the beverage in the, cylindrical vessel will be

Your answer:  ·  Correct: C
Explanation

Let the common radius be r. Volume of a hemisphere = (2/3)πr^3. The cylinder’s radius equals r and “radius is 50% more than its height” means r = 1.5·h, so h = (2/3)r. Cylinder volume = πr^2h = πr^2·(2/3)r = (2/3)πr^3. Hence the hemisphere and the cylinder have equal volumes, so the entire contents of the hemisphere exactly fill the cylindrical vessel — 100% of the juice is transferred. This conclusion matches the worked solution presented in the given source.
