Find the area and the circumference of the circle. Round your answers to the nearest hundredth.

Alik [6]

Answer:

$area = 200.96 \: {units}^{2} \\ circumfrence = 50.24 \: units$

Step-by-step explanation:

The formula to find the area and circumference of a circle is:

$area = \pi {r}^{2} \\ circumfrence = 2\pi \: r$

*note that pi is 3.14* Therefore the area is:

$formula = \pi {r}^{2} \\ 3.14 \times {8}^{2} = \\ 3.14 \times 64 = 200.96$

Therefore the circumference is:

$formula = \: 2\pi \: r \\ (2)(3.14)(8) = \\ 3.14 \times 16 = 50.24$

The given options are:

(A)x+y = 20
(B)7 apps and 14 movies
(C)x-y= 20
(D)y=-x+ 20
(E)8 apps and 12 movies
(F)xy= 20

Answer:

(A)x+y = 20
(D)y=-x+ 20
(E)8 apps and 12 movies

Step-by-step explanation:

If Elizabeth has a combined total of 20 apps and movies.

Where:

Number of apps=x

Number of Movies =y

Then:

Their total,

x+y=20 (Option A)

If we subtract x from both sides

x+y-x=-x+20

y=-x+20 (Option D)

In Option E

8 apps and 12 movies add up to 20. Therefore, this could also apply.

The density of people (number of people per mile) during the evening rush hour for the 5 mile stretch along a certain sidewalk i

Kisachek [45]

Answer:

a. $\int\limits^5_0 {f(x)} \, dx$

Step-by-step explanation:

Since f(x) is the function for the populational density at a certain sidewalk for a 5 mile stretch, a definite integral of that function will yield the total number of people within the integration intervals. If we are interested in the number of people in the whole 5 mile stretch, we must integrate f(x) from x = 0 miles to x = 5 miles:

$\int\limits^5_0 {f(x)} \, dx$

Therefore, the answer is alternative a.
