Find the surface area of the figure. For calculations involving pi , give both the exact value and an approximation to the neare
emmasim [6.3K]

Answer:

exact: SA = 260π in.²

approximate: SA = 816.81 in.²

Step-by-step explanation:

SA = 2πr² + 2πrh

r = 10 in.

h = 3 in.

SA = 2πr(r + h)

SA = 2π(10 in.)(10 in. + 3 in.)

SA = 260π in.²

SA = 816.81 in.²

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?
kompoz [17]

Answer:

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

Step-by-step explanation:

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

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

Donde:

D - Diámetro del tubo, medido en centímetros.

v - Velocidad del flujo, medida en centímetros por segundo.

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

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

Q \approx 98.175\,\frac{cm^{3}}{s}

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