Answer: The area of the plate is 81.67 in^2

Step-by-step explanation:

If we have a circle of radius R, the area of this circle can be computed as:

A = pi*R^2

where pi = 3.14

And the circumference is:

C = 2*pi*R

and we know that this is equal to 32 in, then:

32in = 2*pi*R

Now we can isolate R, and we get:

32in/(2*pi) = R

32in/(2*3.14) = R = 5.1 in

Then the area of the plate is:

A = 3.14*(5.1in)^2 = 81.67 in^2

Step-by-step explanation:

Someone calculated his or her average speed to 18.36 Miles per hour (mph) Calculate your average speed This calculation will help you calculate your average speed when you have covered a certain distance over a certain time.

Answer:

2 mph

Step-by-step explanation:

if we divide our miles by our time with the equation d for distance and t for time we'll get this

d/t = s (s to represent the speed

now time to plug in our equation

25/12.5 = 2

we now have our answer of 2 miles per hour

Answer: V = 1731.8Ft³

Step-by-step explanation:

v = πr²h

Radius is half of the diameter ⇒ 21/2 = 10.5

V = π(10.5)²(5)

V=π(110.5)(5)

V = π(551.25)

V = 1731.8Ft³

The solution is : the volume of the pool is V = 1731.8Ft³.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

Here, we have,

we know that,

the volume of the cylinder is:

v = πr²h

Radius is half of the diameter

⇒ 21/2

= 10.5

so, we get,

V = π(10.5)²(5)

V=π(110.5)(5)

V = π(551.25)

V = 1731.8Ft³

Hence, The solution is : the volume of the pool is V = 1731.8Ft³.

Answer:

The y-intercept is (0,3)

Step-by-step explanation:

Answer:216X

Step-by-step explanation:

Volume of the sphere = 4/3 πr³

radius r = 6 inches

Volume = 4/3 π(6)³

⇒ 4/3(216)π

⇒ 472π

⇒ 288π cubic inches

Volume of  a cylinder = π r²h

radius r = 6 inches

height h = 6 inches

Volume = π(6)²(6)

⇒ 6³π

⇒ 216π cubic inches

Difference between the volumes = 288π - 216π = 72π

Question:

In New York City at the spring equinox there are 12 hours 8 minutes of daylight. The  longest and the shortest days of the year vary by 2 hours 53 minutes from the equinox.  In this year, the equinox falls on March 21. In this task, you'll use a trigonometric function  to model the hours of daylight hours on certain days of the year in New York City.

- Find amplitude and the period of the function

- Create a trigonometric function that describes the hours of sunlight for each day of the year

- Then use the function you built to find how fewer daylight hours February 10 will have then March 21

Answer:

(a)

[tex]A = 2.883[/tex]  --- Amplitude

[tex]T = 365[/tex] ---- Period

(b) Trigonometry function

[tex]f(x) = 12.133 + 2.883sin(\frac{2\pi}{365}[x - 80])[/tex]

(c) [tex]Hours= 1.794[/tex]

Step-by-step explanation:

Given

[tex]Average\ Sunlight = 12hr\ 8 min[/tex]

[tex]Variance = 2hr\ 53min[/tex]

Solving (a): Amplitude (P) and Period (T)

The amplitude is the amount of time the longest and the shortest day vary.

So

[tex]A = 2\ hr\ 53\ min[/tex]

Convert to hours

[tex]A = 2\ + \frac{53}{60}[/tex]

[tex]A = 2+0.883[/tex]

[tex]A = 2.883[/tex]

The period (T) is the duration i.e 1 year

[tex]T = 1\ year[/tex]

Assume no leap year

[tex]T = 365[/tex]

Solving (b): Trigonometry function

The function follows a sinusoidal pattern and the general form is:

[tex]f(x) = \mu+ Asin(\frac{2\pi}{T}(x -n))[/tex]

Where

[tex]\mu = Average\ Value[/tex]

[tex]\mu = 12\ hr 8\ min[/tex]

Convert to hours

[tex]\mu = 12 + \frac{8}{60}[/tex]

[tex]\mu = 12 + 0.133[/tex]

[tex]\mu = 12.133[/tex]

[tex]A = 2.883[/tex]  --- Amplitude

[tex]T = 365[/tex] ---- Period

[tex]n = Equinox[/tex]

[tex]n = March\ 21[/tex]

[tex]March\ 21st = 80th\ day[/tex]

So:

[tex]n= 80[/tex]

The function becomes:

[tex]f(x) = \mu+ Asin(\frac{2\pi}{T}(x -n))[/tex]

[tex]f(x) = 12.133 + 2.883sin(\frac{2\pi}{365}[x - 80])[/tex]

Solving (c): Fewer daylight hours will Feb. 10 have.

[tex]Feb\ 10 = 41st\ day[/tex]

So:

[tex]f(x) = 12.133 + 2.883sin(\frac{2\pi}{365}[x - 80])[/tex]

[tex]f(41) = 12.133 + 2.883sin(\frac{2\pi}{365}[41 - 80])[/tex]

[tex]f(41) = 12.133 + 2.883sin(\frac{2\pi}{365}[-39])[/tex]

[tex]2\pi = 360^\circ[/tex]

So:

[tex]f(41) = 12.133 + 2.883sin(\frac{360}{365}[-39])[/tex]

[tex]f(41) = 12.133 + 2.883sin(-38.466)[/tex]

[tex]f(41) = 12.133 - 2.883*0.6221[/tex]

[tex]f(41) = 10.339[/tex]

The fewer daylight hours is the calculated as:

[tex]Hours= Average - f(41)[/tex]

[tex]Hours= \mu - f(41)[/tex]

[tex]Hours= 12.133 - 10.339[/tex]

[tex]Hours= 1.794[/tex]

Answer:

Step-by-step explanation:

Area Triangles

Area = 1/2 b * h

In a right triangle the two smaller sides are used to find the area

A = 1/2 6 * 4.5

A = 1/2 * 27

A = 13.5

But there are 2 of them so that the area = 2* 13.5 = 27

Area Front side

Area = L * w

L = 13

w = 6

Area = 13 * 6

Area = 78

Area Back side

Area = L * W

Area = 4.5 * 13

Area = 58.5

Bottom  Area

Area = L * W

L = 13

W = 7.5

Area = 13 *  7.5

Area = 97.5

Total Area = 58.5 + 78 + 27 + 97.5

Total Area = 163.5 + 97.5

Total Area = 261
