Answer:
Therefore,
The volume of the geode, rounded to the nearest tenth is 640.1 feet³.
Step-by-step explanation:
Given:
Geode shaped approximately like a cylinder. such that
Height = h = 26 feet
Diameter = d = 5.6 feet

To Find:
volume of the geode = ?
Solution:
Geode shaped approximately like a cylinder,
So, Volume of Cylinder is given by,

Where,
Height = h
Radius = r
pi = 3.14
Substituting the values we get

Therefore,
The volume of the geode, rounded to the nearest tenth is 640.1 feet³.
