Question

a conical cup has a height of 21 cm and the diameter of its base is 18 cm.then the amount of water it can hold is​

Answer 1

Step-by-step explanation:

Amount of water a conical cup contains=Volume of cone.

Volume of Cone=1/3πr²h

Given: h=21cm, d=18cm r=18/2=9cm.

Volume=1/3(22/7)(9)²(21)

=1728cm³.

Answer 2

Answer:

1782cm³

Step-by-step explanation:

Given:

height = 21cm

diameter = 18cm

radius = diameter/2

radius = 18/2

radius = 9cm

To Find:

Amount of water it can hold means volume = ?

Solution:

Volume = πr²h/3

Volume = 22/7*9*9*21/3

Volume = 1782cm³
