What is the surface area of a dome (a half sphere) with a radius of 6 meters?
72 pi meters squared
48 pi meters squared
24 pi meters squared
144 pi meters squared

Answers

Answer 1

Answer: 72π meters squared.

Step-by-step explanation: Given that the radius is 6 meters, use the sphere surface area formula to find the surface area of the half-sphere;

Replace the value in the formula: A=4πr² → A=4π6²Solve the exponent first: A=4π6² → A=4π36The order of the multiples does not affect the total, so we can multiply 4 times 36 first: A=4π36 → A=144π144π is the surface area of the whole sphere, so half the sphere will be 72π. In conclusion, the surface area of the dome will be 72π meters squared.

376.99 cm^3 or 120π cm^3

Step-by-step explanation:

The volume of a cone is 1/3(B*h) where B is the base area and h is height.

The base of a cone is a circle.

Area of a circle=πr^2

Area of the circle=π6^2

Area of the circle=36π

Plug it into the formula for the volume:

V=1/3(36π*10)

V=1/3(360π)

V=120π

V=376.99

Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una. ¿Cuánto pagó por todo?

Answers

Answer:

Costo Total= $38,680

Step-by-step explanation:

Dada la siguiente información:

Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una.

Para calcular el costo total, debemos usar la siguiente formula:

Costo Total= costo unitario * cantidad adquirida

Costo Total= 408*16 + 732*27 + 652*19

Costo Total= $38,680

The total amount of everything including sewing machines, sound systems, and washing machine is $38,680.

What is the cost price?

The cost price refers to the original price of the items, it is the total amount of money that costs a manufacturer to provide a given product.

The unit cost of sewing machines = 408

The unit cost of a sound system = 732

The unit cost of a washing machine = 652

Total cost = 408 × 16 + 732 × 27 + 652 × 19

                = 6528 + 19764 + 12388

                = $38,680

Therefore, the total amount of everything including sewing machines, sound systems, and washing machine is $38,680.

Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.

Answers

Step-by-step explanation:

Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.

3w + 1 = 7 Subtract 1 from both sides

3w = 6 Divide 3 from both sides

w = 2

Given function is,

f(x) = [tex]\sqrt{x}[/tex]

If the given function is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] Or 1.5,

Transformed function will be,

h(x) = [tex]\frac{3}{2}[f(x)][/tex]

h(x) = [tex]\frac{3}{2}(\sqrt{x})[/tex]

Further function 'h' is shifted 1 units upwards,

g(x) = h(x) + 1

g(x) = [tex]\frac{3}{2}(\sqrt{x} )+1[/tex]

Domain of the function → x ≥ 0 Or [0, ∞)

Range of the function → y ≥ 1 Or [1, ∞)

Transformations done → Parent function f(x) is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] then shifted 1 unit upward.
