An ice cream cone has a diameter of 4.2 cm and a height of 11.5 cm. What is the volume of the cone? A. 18.6 cm³ B. 53.1 cm³ C. 2
777dan777 [17]

Answer:

B. 53.1 cm³

Explanation:

\sf volume \ of \ cone:  \dfrac{1}{3} \pi r^2h   \ \        \ \ (r \ is \ radius, \ h \ is \ height)

Here Given:

height: 11.5 cm

diameter: 4.2 cm

radius: d/2 = 4.2/2 = 2.1

Volume:

\sf \cdot \  \dfrac{1}{3} \pi r^2h

\sf \cdot \  \dfrac{1}{3} (3.14) (2.1)^2(11.5)

\sf \cdot \ 53.11 \ cm^3 ≈ \sf 53.1 \ (rounded \ to \ nearest \ tenth)

en una caja hay 8 canicas cinco rojas y tres verdes y la Bola que se retira no se reemplaza determina Cuál es la probabilidad de
postnew [5]

Answer: 0.107

Step-by-step explanation:

En una caja tenemos 8 canicas.

5 son rojas

3 son verdes.

Se retira una canica, y no se remplaza.

Quiero calcular la probabilidad de sacar dos canicas verdes.

La probabilidad de sacar una canica verde en el primer intento, es igual al cociente entre el numero de canicas verdes y el numero total de canicas.

p1 = 3/8  

Ahora, en el segundo intento, en la caja voy a tener 2 canicas verdes (por que ya saque una) y 7 canicas en total. Entonces la probabilidad va a ser:

p2 = 2/7.

Y la probabilidad conjunta (es decir, la probabilidad de sacar las dos canicas de color verde) va a ser igual al producto de las probabilidades individuales.

P = p1*p2 = (3/8)*(2/7) = 0.107
