# Hexagonal pyramid

Base of the pyramid is a regular hexagon, which can be circumscribed in a circle with a radius of 1 meter. Calculate the volume of a pyramid 2.5 meters high.

Result

V =  2.17 m3

#### Solution:

$V=1/3 \cdot \ 2.5 \cdot \ (6 \cdot \ \sqrt{ 3 }/4 \cdot \ 1^{ 2 })=2.17 \ \text{m}^3$
