A cylinder has radius R = 3.7 and height H = 5.6 both measured in inches. What is the volume of this cylinder measured in cm3? (

lorasvet [3.4K]

Answer:

<h2>The volume is $3946.17cm^3$ </h2>

Step-by-step explanation:

We need to convert the radius and the height to cm first

1 cm = 0.393701 in

r (cm)= 3.7 in

$h(cm)= \frac{3.7}{0.393701}= 9.398 cm$

1 cm = 0.393701 in

h (cm)= 5.6 in

$h(cm)= \frac{5.6}{0.393701}= 14.22 cm$

The formula the volume of cylinder is

$volume= \pi r^2h\\\\volume= 3.142*9.398^2*14.22\\volume=3946.17cm^3$

Kaylis [27]

Answer:

Marcela tardó 6 horas y Roberto tardó 8 horas.

Step-by-step explanation:

Dado que Marcela tardó dos horas menos que Roberto en recorrer una distancia en bicicleta, y sabiendo que el producto de los dos tiempos es de 48 horas, para determinar cuánto tardó cada uno se debe realizar el siguiente cálculo:

M = X

R = X + 2

X x (X + 2) = 48

8 x 6 = 48

Por lo tanto, Marcela tardó 6 horas y Roberto tardó 8 horas.
