Question

A cyclinder having diameter 40cm contain4/5 of water if a cone having eqaul to 3/4 the time the hieght of the cylinder how much water will overflow from the cylinder​

Answer 1

Explanation:

Volume of cylindrical container=π×r

2

×h

where r=

2

16

=8cm and h=40cm

Volume of cylindrical container=π×8

2

×40=2560×πcm

3

Volume of ice-cream cone = Volume of cone + volume of hemisphere =

3

π×r

2

×h

+

3

2×π×r

3

Here r=

2

4

=2cm and h=12cm

Volume of ice-cream cone =

3

π×2

2

×12

+

3

2×π×2

3

Volume of ice-cream cone =21.33×πcm

3

Number of cones =

Volume of cone

Volume of cylindrical container

=

21.33×πcm

3

2560×πcm

3

=120

Hence number of cones =120
