Un prisma cuadrangular regular tiene 4 m de arista de la base y 6m de altura Calcula el area y el volumen
mario62 [17]

Answer:

El área y volumen del prisma cuadrangular mencionado son respectivamente:

  • <em>Área =</em> 16m^{2}
  • <em>Volumen =</em> 96m^{3}

Step-by-step explanation:

Para solucionar este ejercicio debes recordar que un prisma cuadrangular tiene como base y como superficie cuadrados, por lo tanto, para calcular el área de dicho cuadrado puedes utilizar la siguiente fórmula:

  • <em>Área de un cuadrado = </em>arista^{2}

Ya que el ejercicio nos da el valor de la arista (4 metros), podemos reemplazarla en la ecuación y calcular:

  • Área de un cuadrado = (4m)^{2}
  • Área de un cuadrado = 16m^{2}

Por último, para calcular el volumen debes multiplicar el área superficial, el área del cuadrado calculado, por la altura del prisma, cuyo valor dentro del enunciado es de 6 metros, de esta forma:

  • <em>Volumen de un prisma cuadrangular = área superficial * altura</em>
  • Volumen de un prisma cuadrangular = 16m^{2} * 6 m
  • Volumen de un prisma cuadrangular = 96m^{3}

Como puedes ver tras los cálculos, <u><em>el área superficial del prisma es de </em></u>16m^{2}<u><em> y su volumen es </em></u>96m^{3}.

Someone help me pls
Wittaler [7]

Answer:

y=1/2x + 3

Step-by-step explanation:

The first thing you need to know is that the slope of a perpendicular line is the opposite reciprocal of the other slope. Find the slope of this line, which is -2. The opposite reciprocal is 1/2. So, you know that the perpendicular line is equal to y=1/2x. Plug the x coordinate (4) in for x to have: y=1/2(4). Multiply 4 by 1/2 to get y=2. Since the y coordinate is supposed to equal 5, add 3 to y=2 to get 5. Since 3 is the amount we added, thats where the y intercept will be. Hope this helped!
