Answer:
Number of cones is 25.
Step-by-step explanation:
Given:-
- A solid sphere of radius 5 cm is melted and recast into smaller solid cones, each of radius 2 can and height 5 cm.
To find:-
- The number of cones.
Solution:-
- Radius of sphere = 5 cm.
Formula used :-
Then,
Volume of the sphere,
Formula used :-
- Radius= 2 cm
- Height = 5 cm
Volume of cone,
Now find the number of cones.
→ Number of cones = 25
Therefore, the number of cones is 25.

- A solid sphere of radius 5 cm is melted and recast into smaller solid cones, each of radius 2 cm and height 5 cm. The number of cones so formed is.
- Radius of sphere (r) 5cm
- Radius of cone (R) 2cm
- height of cone 5cm
Let,
- Number of cone be x
† Volume of sphere = No. of cone × Volume of each cone
- 25 cone are formed in a solid sphere
