Question

Anil and Bela ordered some ice creams in a shop Anil wants it to be in a cone with a hemispherical topping and Bela in a cylindrical Cup the height of the cone and the cylinder are 5 cm and radius of cone cylinder and hemisphere are all 3.5 CM​

Answer 1

here is ur answer dude.....

Height of cylindrical container =15cm

Volume of cylinder =πr

2

h

=π×36×15

=540πcm

3

Now, as it has to be divided among 10 children

∴ Dividing volume by 10=

10

540

=54πcm

3

Volume of cone + Volume of hemispherical top = Volume of ice-cream in it.

⇒

3

1

πr

2

h+

=πr

2

h

⇒

1

πr

2

(4r)+

3

2

πr

3

=54π

⇒

3

1

πr

3

(4+2)=54π

⇒2r

3

=54⇒r=3

Hence, the radius of icecream cone =3 cm.
