Question

The radius of sphere is 12cm . How many sphere can be made from it of 6cm radius

Answer 1

4 spheres of radius 6cm can be made by the sphere of radius 12 cm

Answer 2

As We know that the radius of the sphere is 12 cm. Firstly we have to find the volume of the sphere.

→ 4/3πr³

→ 4/3 × 3.14 × (12)³

→ 4/3 × 3.14 × 12 × 12 × 12

→ 7234.56 cm³

Now, We have to find the volume of sphere of radius (6 cm).

→ 4/3πr³

→ 4/3 × 3.14 × (6)³

→ 4/3 × 3.14 × 6 × 6 × 6

→ 904.32 cm³

Finally, After dividing the volume of large sphere with the volume of small sphere then we can get the number of sphere that Formed into it.

→ 4/3πr³/4/3πr³

→ 7234.56/904.32

→ 8 Spheres

Hence,

The total number of Spheres formed is 8.
