Question

A. The particle shown in Hg is made of hemisphere f lone
aum find.
difference between the
volume of cone & hemisphere
is 6cm & diameter of Sphere is​

Answer 1

Answer:

Let the number of spherical balls be n. Then, the volume of the cone will be equal to the sum of the volumes of the spherical balls. The radius of the base of the cone =

2

6

cm=3cm

and the radius of the sphere =

2

1

cm.

Now, the volume of the cone

=

3

1

π×3

2

×10cm

3

=30πcm

2

and the volume of each sphere

=

3

4

π(

2

1

)

3

cm

3

=

6

π

cm

3

Hence, we have

n

6

π

=30π⇒n=6×30=180

Hence, the required number of balls =180
