What is the approximate volume of the cone?
Mnenie [13.5K]

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr²\frac{h}{3}

We know the radius = 12

and the height = 8

Substitute :

V = π12²\frac{8}{3}

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = \frac{2^4*3^2*8\pi }{3}

Cancel the common factor - 3 :

V = 2^4 * 8 * 3\pi

Multiply 8 and 3π :

V = 2^4 * 24\pi

Solve the exponent :

V = 16 * 24\pi

Multiply :

V = 384\pi

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³

Un grupo de amigos quiere realizar una actividad de recaudación de fondos, para ello han decidido vender pizzas. La primera pizz
trasher [3.6K]

Answer:

Los Amigos deberían comprar pizzas vendidas por la primera pizzería que cuestan S / 0.032 por cm² para obtener más ganancias.

Step-by-step explanation:

Los parámetros dados son;

El diámetro de las pizzas vendidas por la primera pizzería = 40 cm

El precio de las pizzas vendidas por la primera pizzería = S / 40

El diámetro de las pizzas vendidas por la segunda pizzería = 25 cm

El precio de las pizzas vendidas por la segunda pizzería = S / 25

El área de las pizzas vendidas por la pizzería = π × D² / 4

El área de las pizzas vendidas por la primera pizzería = π × 40² / 4≈1256.64 cm²

El costo por unidad de superficie de las pizzas vendidas por la primera pizzería = S / 40 / (1256.64 cm²) ≈ S /0.032/cm²

El área de las pizzas vendidas por la segunda pizzería = π × 25² / 4≈490.87 cm²

El costo por unidad de superficie de las pizzas vendidas por la primera pizzería = S / 25 / (490.87 cm²) ≈ S /0.051/cm²

Las pizzas vendidas por la primera pizzería que cuestan S /0.032/cm² s más baratas y producirán mejores ganancias que las pizzas vendidas por la segunda pizzería que cuestan S /0.051/cm²

Por lo tanto, los amigos deben comprar pizzas vendidas por la primera pizzería que cuestan S /0.032 / cm² para obtener más ganancias.

The population of Hawaii is growing by about 5% per year. If that rate were to continue, how long would it take for the populati
11111nata11111 [884]

Answer:

  14.2 years

Step-by-step explanation:

The multiplier of the population each year is 1 +5% = 1.05, so after n years the population has been multiplied by 1.05^n. You want to find the value of n that makes this expression equal to 2:

  2 = 1.05^n

  log(2) = n·log(1.05) . . . . . take logarithms

  log(2)/log(1.05) = n ≈ 14.2

Growing at a rate of 5% per year, it will take about 14.2 years for the population to double.
