Answer:
The height of the cylinder is 10 cm.
Explanation:
1. The volume of a cylinder is given by
-V = pi r^2 h where r is the radius and h is the height
- 90 pi = pi r^2 h
2. We know the radius is 3
-90 pi = pi (3)^2 h
-90 pi = 9 pi h
3. Divide each side by 9 pi
- 90 pi /9 pi = 9 pi h / 9pi
- 10 =h
The height of the cylinder is 10 cm.
