Hexa pyramid

The base of the regular pyramid is a hexagon, which can be described by a circle with a radius of 1 m. Find the volume of the pyramid 2.5 m high.

Correct result:

V =  2.1651 m3

Solution:

r=1 m h=2.5 m  S1=34⋅ r2=34⋅ 12≐0.433 m2 S=6⋅ S1=6⋅ 0.433≐2.5981 m2  V=13⋅ S⋅ h=13⋅ 2.5981⋅ 2.5=2.1651 m3
