- V=Volume
- <em>π = pi</em>
- <em> </em>r=radius
Provided information:-
What we need in order to find the Volume:-
How to find the radius if we have the diameter?
- Since the radius is exactly one-half of the diameter, we divide the diameter by 2:-
Replace d with 10:-
Therefore, the radius of the sphere is

✓ Now we have all the required information in order to find the volume of the sphere.
✳︎Substitute 5 in lieu of r:-
➪On simplification,
◈ Next, write the value of π (3.14…)
On further simplification,
Final Step:- Multiply the numbers.
The answer has been rounded to the nearest tenth (one place after the decimal point)
Therefore, we conclude that the volume of the sphere is
