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}.

A typical running track is an oval with 74-m-diameter half circles at each end. a runner going once around the track covers a di
denpristay [2]

Answer:

Her centripetal acceleration during the turn at each end of the track is 0.432\, \frac{m}{s^{2}}

Step-by-step explanation:

Total distance covered in one round , D= 400 m

Time taken to cover one round , T = 1 min 40 s = 100 sec

Speed of runner , V=\frac{D}{T}=\frac{400}{100}\, \frac{m}{s}= 4.0\, \frac{m}{s}

Now centripetal acceleration is given by

a_c=\frac{V^{2}}{R}

where V= 4.0\frac{m}{s}

Radius, R= \frac{Diameter}{2}=\frac{74}{2}m=37\, m

\therefore a_c=\frac{4^{2}}{37}\, \frac{m}{s^{2}}=0.432\, \frac{m}{s^{2}}

Thus her centripetal acceleration during the turn at each end of the track is 0.432\, \frac{m}{s^{2}}
