Question

What is the height of a hemisphere if it has a radius of 0.8m (80cm)?

Answer 1

There, radius = height.

So Height = 0,8 m = 80 cm

Answer 2

The height of a semisphere is equal a radius of this hemisphere.

But... if we can talk about the height of the hemisphere ;)

R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
