What is the total surface area of the square pyramid in square inches?

Answers

Answer:

208

............

The total surface area of the square pyramid is 208 square inches.

What is Area?

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -

V = ∫∫F(x, y) dx dy

Given is to find the total surface area of the square pyramid in square inches.

We can write the total surface area of the square pyramid as -

A{total} = A{square} + 4 x A{Δ}

A{total} = (8 x 8) + (4 x 1/2 x 8 x 9)

A{total} = 64 + (16 x 9)

A{total} = 208 square inches

Therefore, the total surface area of the square pyramid is 208 square inches.

Por un tubo de 2.5 cm de diámetro fluye agua con una repidez de 20 cm/s ¿Cuál es el valor del flujo y el gasto del agua?

Answers

Answer:

El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.

Step-by-step explanation:

El gasto del agua ([tex]Q[/tex]), medido en centímetros cúbicos por segundo, es el flujo que pasa a través del tubo. La ecuación para determinar el gasto es:

[tex]Q = \frac{\pi}{4}\cdot D^{2}\cdot v[/tex] (1)

Donde:

[tex]D[/tex] - Diámetro del tubo, medido en centímetros.

[tex]v[/tex] - Velocidad del flujo, medida en centímetros por segundo.

Si sabemos que [tex]D = 2.5\,cm[/tex] y [tex]v = 20\,\frac{cm}{s}[/tex], entonces el flujo y gasto del agua es:

[tex]Q = \frac{\pi}{4}\cdot (2.5\,cm)^{2}\cdot \left(20\,\frac{cm}{s} \right)[/tex]

[tex]Q \approx 98.175\,\frac{cm^{3}}{s}[/tex]

El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.

Answer:

  26.13 ft²

Step-by-step explanation:

The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.

  Semicircle area = (1/2)(πr²)

  semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²

The area of the two right triangles is ...

  total triangular area = (3 ft)(4 ft) = 12 ft²

Then the area of the figure is ...

  figure area = semicircle area + total triangular area

  = 14.13 ft² + 12 ft² = 26.13 ft²
