Answer:

3/5pi

Step-by-step explanation:

The formula of getting the arc length is

arc length = angle * pi / 180 * r

arc length = 60 * pi / 180 * 5

arc length = 300 * pi / 180

arc length = 5pi / 3

Answer:

15.26km

Step-by-step explanation:

Con la informacion de la pregunta e hecho un diagrama de la situacion. Podemos ver en el diagrama que el recorido forma un triángulo rectángulo. Entonces para saber la distancia que recorreria por el camino recto desde su casa a su trabajo tendriamos que calcular el valor de x, que se puede calcular usando el teorema de pitagoras que es el siguiente.

$a^{2} + b^{2} = c^{2}$

donde a y b son el ancho y el alto del triangulo y el c seria x

$8^{2} + 13^{2} = x^{2}$

$64 + 169 = x^{2}$

$233 = x^{2}$

$15.26 = x$

Finalmente, podemos ver que la distancia seria 15.26km

Explain one way to add 3 digit numbers

Ray Of Light [21]

You can add them like this:

so if 156 + 213 + 109 was the equation then you would

first put them in order from biggest to smallest

213
156
+109
-----------

then add:

¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )

then you get the answer 478!

hope that helps :)
