Question

A juice seller serves his customers using a glass as shown in figure .The inner diameter of the cylindrical glass is 6.5 cm but the bottom of the glass has a hemispherical portion raised ,which reduces the capacity of the glass .If the height of the glass is 30cm ,find the apparent capacity of the glass and its actual capacity.

Answer 1

Answer:

for ans and solution

Apparent capacity of glass = volume of cylinder .

•actual capacity of glass = volume of cylinder - volume of hemisphere

1.) Volume of cylinder .

Given inner diameter of the glass = 6.5 cm

So radius = r = diameter /2

= 6.5/2

= 3.25cm

Height= 30 cm

Volume of cylindrical glass = πr²h

=3.14×3.25×3.25×30

= 994.9875cm³

2.) Volume of the hemisphere

Radius of hemisphere = r= 3.25 cm

Volume of the hemisphere=2/3πr³

=2/3×3.14×3.25^3

=71.8602083cm³

Actual volume = volume of cy. - volume of hemisphere

= 994.9875cm³-71.8602083cm³

=923.127292

Hope it helps
