Answer :
›»› The volume of water is 36π cm³.
Given :
- A glass in the form of a right circular cylinder is half full of water. Its base radius is 3 cm and height is 8 cm.
To Find :
- Volume of water = ?
Solution :
- Radius of glass = 3 cm.
- Height of glass = 8 cm.
As we know that
→ Volume of cylinder = πr²h
→ Volume of cylinder = π * (3)² * 8
→ Volume of cylinder = π * 9 * 8
→ Volume of cylinder = π * 72
→ Volume of cylinder = 72π
Now,
A glass is half full of water.
→ Volume of water = Volume of glass/2
→ Volume of water = 72π/2
→ Volume of water = 36π
║Hence, the volume of water is 36π cm³.║
Correct option is (b) 36π cm³.
