Question

77. A hemispherical bowl of internal diameter 24 cm is full of liquid. The liquid is to be filled into
cylindrical shaped bottles each of the radius 2 cm and height 6 cm. How many bottles are needed
to empty the bowl?
please solve it ......
step by step......​

Answer 1

Answer:

According to the problom  

Given that  

Radius of hemispherical bowl = 9 cm

Hence the volume of bowl =  2 πr  ^2

                                                 3

Implies that  

=  2×22×9×9×9

   3   7

Implies that  

=1527.42cm ^3

 

Since height of the bottle (h) = 4cm  

and Diameter of the cylindrical bottles=3cm

Implies that  

radius = 1.5cm

Hence ,  

the volume of the cylindrical bolltle = πr ^2 h

== 22×1.5×1.5×4cm^3

     7

   

Let the number of bottle be (n)

Implies that  

=n×22×9×9×9

       7

implies that  

=n=        2              ×9×9×9

​           3*1.5*1.5*4

implies that  

n=5

Hence the number of bottle is 54.
