The height of hemisphere is equal to its

Options

A. circumference
B. capacity
C. surface
D. radius

Answer

To solve the question "The height of a hemisphere is equal to its:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Hemisphere**:
- A hemisphere is half of a sphere. It has a flat circular base and a curved surface that forms the upper half.

2. **Identify the Components**:
- The radius (R) of the hemisphere is the distance from the center of the base to any point on the circular edge.
- The height (h) of the hemisphere is the perpendicular distance from the base to the topmost point of the curved surface.

3. **Visualize the Height**:
- The height of the hemisphere can be visualized as the radius of the sphere from which the hemisphere is derived.

4. **Relate Height to Radius**:
- In a hemisphere, the height is equal to the radius. This is because the highest point of the hemisphere is directly above the center of the base, and the distance from the center to the top is the same as the radius.

5. **Conclusion**:
- Therefore, the height of the hemisphere is equal to its radius.

### Final Answer:
The height of a hemisphere is equal to its radius.
