Question

a hemisphere bowl of internal radius 15cm.contains a liquid.the liquid is to be filled into cylindrical bottles od diameter 5cm and height 6cm. how many bottles are necessary to empty the bowl​

Answer 1

Answer:

60 bottles

Step-by-step explanation:

Firstly the liquid is occupying same volume in the bowl as well as when fully poured i.e.

Volume of hemispherical bowl = n * Volume of bottles

where n = number of bottles to be filled

so V of Bowl = 2/3 π r^2 = 7069 cm^3

and V of bottles = V of cylinder = π r^2 H

= 117.81 cm^3

so n = V of bowl/V of bottles

n = 7069/117.81 = 60 bottles
