The diameter of a circle is 10 m. Find its area to the nearest tenth.
Readme [11.4K]

Answer:

78.54 m^2

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

Area of the circle = πr^2

Also

Diameter = 2r

10 = 2r

r = 5

So, the area of the circle is

=  3.14 × 5^2

= 78.54 m^2

4. Acertijo.
7nadin3 [17]

Las edades de cada uno de los integrantes del acertijo son:

  • Luisa = 3 años
  • Juan = 6 años
  • Carmen = 8 años

Cálculo por medio de ecuaciones.

Para identificar la edad de cada persona en el acertijo, se pueden crear ecuaciones con la información brindada, aunque, primero se deben asignar variables:

  • <em>L = Edad de Luisa</em>
  • <em>J = Edad de Juan</em>
  • <em>C = Edad de Carmen</em>

Teniendo estas variables se procede a crear las ecuaciones, la primera parte del ejercicio dice que "<em>Luisa es 3 años más joven que su hermano Juan</em>", entonces la ecuación podría ser:

  • 1. J = L + 3

La segunda parte dice que "<em>su hermana Carmen es 2 años mayor que Juan</em>", entonces:

  • 2. C = J + 2

Y la tercera parte menciona que "<em>Juan tiene el doble de edad que Luisa</em>", por lo tanto:

  • 3. J = 2L

Se realiza el método de reducción con la primera y la tercera ecuación, para calcular el valor de L:

  • 1. J = L + 3 (<em>Se multiplica por (-1) puesto que la variable que se busca reducir es J</em>)
  • 3. J = 2L

Entonces se calcula:

  • - J = - L - 3
  •  J = 2L

 

  • 0 = L - 3 (<em>El número 3 que está restando se pasa a sumar al otro lado de la igualdad</em>)
  • 3 = L
  • <u>L = 3</u>

Teniendo el valor de L, se calcula el valor de J con la tercera ecuación:

  • J = 2L
  • J = 2 * 3
  • <u>J = 6</u>

Y con el valor de J, se calcula el valor de C con la segunda ecuación:

  • C = J + 2
  • C = 6 + 2
  • <u>C = 8</u>

De esta forma, se calcula que <u>las edades de Luisa, Juan y Carmen son: 3 años, 6 años y 8 años respectivamente</u>.

The surface area of the world is about 7/10 water. If a very small, non-dangerous meteoroid lands on the earth, what is the prob
galben [10]

Answer: 3/10 probability

Step-by-step explanation:

We are telling the probability with tenths, so we can say that the probability of the meteoroid landing on Earth is 3/10.

If the surface area of the world is approximately 7/10, or 70 percent, water, there is approximately 3/10, or 30 percent, chance of the meteoroid hitting land.

I'm pretty sure, at least ^_^
