Answer: 16.76

Explanation:

1. A circle is 360°, we know the white sections are both 120°.

120° + 120° = 240°

360° - 240° = 120°

Therefore the shaded section is 120°

2. Using A = πr^2, we can find the total area of the circle. We know the radius is 4 from the given data.

A = π (4)^2

A = π (16)

A = 50.27

3. 120° is 1/3 of 360°, so we can divide the area we found by 3 to find the area of the shaded section.

A = 50.27 / 3

A = 16.755

A = 16.76

Area of sector................................

sveticcg [70]

Answer:

A ≈ 25.1 cm²

Step-by-step explanation:

the area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{\frac{4\pi }{9} }{2\pi }$

= π × 6² × $\frac{\frac{4\pi }{9} }{2\pi }$

= 36π × $\frac{\frac{4\pi }{9} }{2\pi }$

= 18 × $\frac{4\pi }{9}$

= 2 × 4π

= 8π

≈ 25.1 cm² ( to the nearest tenth )

Un automóvil se desplaza 30 1/5 millas en 2/3 de hora. ¿Cuál es la velocidad promedio en millas por hora, del automóvil?

yarga [219]

Queremos encontrar la velocidad promedio de un automóvil dado que conocemos cuanto se desplaza y cuanto tarda en realizar ese desplazamiento. Veremos que la velocidad promedio es 45.3 millas por hora.

Recordar que definimos velocidad promedio como el cociente entre la distancia recorrida y el tiempo que se tarda en recorrer esa distancia.

Aca tenemos:

Desplazamiento = (30 + 1/5) cm

Tiempo = (2/3 horas)

Entonces la velocidad esta dada por:

$V = \frac{(30 + 1/5)mi}{2/3 h} = \frac{(151/5)mi}{2/3 h} = 45.3 mi/h$
