Answer 1

Answer: 24times

Explanation:

Formula for the volume of a cylinder = πr²h

Volume of the cone = 1/3πr²h

Therefore the volume of the cylinder = 22/7 x 10² x 20

= 22/7 x 10 x 10 x 20

= 6285.71cm³

Therefore , the volume of the cone = 1/3 x 22/7 x 5² x 10

= 1/3 x 22/7 x 5 x 5 10

= 5500/21

= 261.9cm³

Therefore the number of times needed to use the completely filled cone to completely filled the cylinder with water = 6285.71/261.9

= 24times.
