¿ cuál será el volumen de una pirámide hexagonal si las aristas de la base miden 8cm, la apotema vale9.93cm y su altura es de 28
dem82 [27]

Answer:

2224.32 cm³

Step-by-step explanation:

La fórmula para el volumen de una pirámide hexagonal = 1/3 (1/2 × P × a) × h

Donde a = Apotema = 9,93 cm

P = Perímetro =

Pirámide hexagonal = 6 × Bordes de la base = 6 × 8 cm = 48 cm

h = Altura = 28 cm

Por eso,

Volumen de la pirámide hexagonal = 1/3 (1/2 (48 × 9.93) × 28 cm

= 1/3 × 238.32 × 28 cm

= 2224.32 cm³

Volumen de la pirámide hexagonal = 2224.32 cm³

A telephone pole casts a shadow that is 34 m long. Find the height of the telephone pole if a statue that is 36 cm tall casts a
Ugo [173]

Answer:

C. 15.9 m

Step-by-step explanation:

Let x be the height of the telephone pole,

Since, the length of the shadow of pole is 34 m,

So, the ratio of the height of the pole and its shadow = \frac{x}{34},

Also, the statue is of 36 cm tall casts a shadow 77 cm long,

Thus, the ratio of the height of pole = \frac{36}{77}

At the same time,

The ratio of height with shadow is same for all objects.

\frac{x}{34}=\frac{36}{77}

x=\frac{34\times 36}{77}=\frac{1224}{77}=15.8961038961\approx 15.9

Hence, the height of the telephone pole is 15.9 m.

Option 'C' is correct.
