Question:

A hemispherical bowl of internal radius 6 cm contains a liquid. This liquid is to be filled into cylindrical shaped small bottles of diameter 2 cm and height 4 cm. How many bottles will be needed to empty the bowl?

Options:

32

37

38

36

Correct Answer:

36

Explanation:

We know that,

Volume of hemisphere = \(\frac{2}{3}\)πr3

Volume of cylinder = πr2

We have,

Radius of bowl = 6 cm

Diameter of small cylindrical bottles = 2 cm

Height of cylindrical bottles = 4 cm

= Volume of hemispherical bowl = \(\frac{2}{3}\) × 3.14 × = 452.16 cm3

= Volume of cylindrical bottles = 3.14 × 12 × 4 = 12.56 cm3

Number of bottles required = \(\frac{452.16 }{12.56 }\) = 36
