Question

A hemispherical bowl of internal radius 9 cm is full of
water. This water is to be filled in cylindrical bottles of
diameter 3 cm and height 4cm. Find the number of
bottles needed to fill the whole water of the bowl.

​

Answer 1

Answer:Number of bottles =54

Step-by-step explanation:

Here this water is to be filled in cylindrical bottles

Therefore volume of hemisphere = n*volume of cylinder

Diameter of cylinder=3 so radius=3/2

2/3*pi*r^3=pi*r^2*h

Pi on both sides cancel

2/3*9*9*9=n*3/2*3/2*4

If u solve u will get

n=54

Therefore 54 bottles required to fill the whole water of the bowl.

Hope it helps
