Question

Height of hemisphere with radius
2cm is​

Answer 1

Answer:

In the half a sphere (hemisphere): In the half cylinder with empty cone: The radius of the hemisphere is r. The height of the hemisphere is r.

Answer 2

4 cm

If the radii of a hemisphere is provided. Then it is easy to approach for it's height. The height will be equal to it's diameter (ignoring thickness). If it's thickness, say 't', is given, then it's height will be equal to (2r + 2t) or 2(r + t).

More about sphere:-

1. SA = $4 \pi r^2$
2. Height = $2(r + t)$
3. Volume = $\frac{4}{3} \pi r^3$.
