2. A right pentagonal pyramid has a volume of 165.17 cubic meters and a height of eight
meters. Complete the following statement.
The pentagonal pyramid has a base area of
how many square meters.

Respuesta :

Answer:

The base area of the pentagonal pyramid is 61.939 square meters.

Explanation:

Given that: the volume of the pyramid = 165.17 cubic meters, its height = 8 meters.

The volume of a pyramid can be determined by:

              volume of the pyramid = [tex]\frac{1}{3}[/tex] × base area × height

So that;

volume of the pyramid = [tex]\frac{1}{3}[/tex] × base area × height

                        165.17 =  [tex]\frac{1}{3}[/tex] × base area × 8

                        165.17 × 3 = 8 × base area

                        495.51 = 8 × base area

     ∴               base area = 61.939 square meters

The base area of the pentagonal pyramid is 61.939 square meters.
