A sphere has a diameter of 11 inches. What is its surface area? Use 3.14 to approximate π. Round to the nearest hundredth if necessary.

Answers

Answer 1

Answer:

The surface area is [tex]379.94in^2[/tex]

Step-by-step explanation:

Given

Shape: Sphere

[tex]D= 11\ in[/tex] - -- Diameter

Required

Determine the surface area (A)

This is calculated using:

[tex]A = 4\pi r^2[/tex]

Where

[tex]r = \frac{1}{2}D[/tex]

[tex]r = \frac{1}{2}*11[/tex]

[tex]r = 5.5[/tex]

So, we have:

[tex]A = 4 * 3.14 * 5.5^2[/tex]

[tex]A = 4 * 3.14 * 30.25[/tex]

[tex]A = 379.94[/tex]

Hence, the surface area is [tex]379.94in^2[/tex]

Answer 2

Answer:

379.94

A rectangle length 34m x width 42m. what is the area of the rectangle

Answers

Answer: 1428m

Step-by-step explanation: The formula for a regular rectangle is l x w = A, or Length x Width = Area. So, if you replace L with 34 and W with 42, you will get your answer by multiplying the numbers

1,428m^2

In this figure, sin(a) = 2/3
What is the value of cos(b) ?

Answers

9514 1404 393

Answer:

  C)  2/3

Step-by-step explanation:

In order to answer the question, we must make an assumption about the given figure. We must assume it is a rectangle, so the left side and right side of the figure are the same length.

The ratio of the right side of the figure to the diagonal is sin(a). The ratio of the left side of the figure to the diagonal is cos(b). If we assume that the left and right sides are the same length, then ...

  sin(a) = 2/3 = side/diagonal = cos(b) = 2/3

_____

Additional comments

The figure does not have enough information to support our assumption. Of the answer choices, only (A) is a reasonable alternative. (The value of the cosine must be at most 1.)

The first attachment shows the figure with sin(a) = cos(b) = 2/3. The second attachment shows the figure with cos(b) = 1/3. There is nothing in the given drawing to say this is an incorrect interpretation. (Drawings cannot be assumed to be to scale.)

What is the initial value of the function f(x)=9(2/3)x+4?

Answers

Answer:

x=-2/3

Step-by-step explanation:

f(x)=9×2/3x+4

0=9×2/3x+4(substitute f (x) =0)

0=9×2/3x+4

0=3×2x+4

0=6x+4

-6x=4( move the variable to left side and change the sign)

Divide both sides.. x=-2/3

The initial value of the function f(x) = [tex]\frac{-2}{3}[/tex]

We have a function f(x) = [tex]9(\frac{2}{3} )x +4[/tex]

We have to find the initial value of the function f(x).

How will you calculate the initial value of a function f(x) ?

We can calculate the initial value of a function f(x) by equating the function f(x) = 0, and find the value of [tex]x[/tex].

In the question given - f(x) = [tex]9(\frac{2}{3} )x +4[/tex]. In order to calculate the initial value of this function - equate f(x) = 0. Therefore -

[tex]9(\frac{2}{3} )x +4 =0\\[/tex]

6x + 4 = 0

x = [tex]\frac{-4}{6}[/tex]

x = [tex]\frac{-2}{3}[/tex]

Hence, the initial value of the function f(x) = [tex]\frac{-2}{3}[/tex]

Find the equation of a line with the given information:
f(- 6) = 8 and f( - 8) = – 1.
Wrote answer in point slope form

Answers

Answer:

[tex]y -8= \frac{9}{2}(x +6)[/tex]

Step-by-step explanation:

Given

[tex]f(-6) = 8[/tex]

[tex]f(-8) = -2[/tex]

Required

Determine the equation in point-slope form

The general function notation is:

[tex]f(x) = y[/tex]

So, in  [tex]f(-6) = 8[/tex]

[tex](x_1,y_1) = (-6,8)[/tex]

[tex]f(-8) = -1[/tex]

[tex](x_2,y_2) = (-8,-1)[/tex]

Calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]

[tex]m = \frac{-1-8}{-8-(-6)}[/tex]

[tex]m = \frac{-1-8}{-8+6}[/tex]

[tex]m = \frac{-9}{-2}[/tex]

[tex]m = \frac{9}{2}[/tex]

The equation is then calculated as:

[tex]y -y_1= m(x-x_1)[/tex]

[tex]y -8= \frac{9}{2}(x - (-6))[/tex]

[tex]y -8= \frac{9}{2}(x +6)[/tex]
