Hey ! there
Answer:
Explanation:
In this question we are provided with a sphere having radius 3 units and value of π is 3.14 . And we're asked to find the volume of sphere .
For finding volume of sphere , we need to know its formula . So ,

Where ,
- r refers to radius of sphere
Solution : -
Now , we are substituting value of π and radius in the formula ,

Simplifying it ,

Cancelling 3 with 3 :

We get ,

Multiplying 4 and 3.14 :

Multiplying 12.56 and 9 :

- Henceforth , volume of sphere having radius 3 units is 113 .04 units cube .
