Question

A hemispherical bowl of internal diameter 30 cm contains some liquid. This is to be filled into cylindrical shaped bottles each of diameter 5 cm and height 6 cm. Find the no. Of bottles necessary to empty the bowl

Answer 1

Answer:

Diameter of hemispherical bowl= 30cm

radius= d/2=30/2= 15cm.

Volume of Hemispherical bowl= 2/3πr³

2/3×22/7×15×15×15= 7071.4cm³

Diameter of cylinderical bowl = 5cm

Radius= d/2=5/2=2.5cm

Height of cylinderical bowl=6cm

Therefore,

Volume of cylinderical bowl= πr²h=22/7×2.5×6

= 47.14cm³.

Numbers of cylinderical bowl necessary to empty the hemispherical bowl = Volume of hemispherical bowl/Volume of Cylinderical bowl..
