Answer:

1249.37 units

Step-by-step explanation:

The circumference of a circle is given as

$C=2\pi \: r$

Given that the circumference of a circle is 7850 units, we can find the radius by substituting and solving for r.

$7850 = 2\pi \: r$

$r = \frac{7850}{2\pi}$

We divide to obtain:

$r = 1249.37$

Therefore the radius of the circle is 1249.37 units

A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va

Setler79 [48]

Answer:

A) $\frac{x}{8}$ gallons

B) Distance between Town A and Town B is $48y$ miles

Step-by-step explanation:

We know, number of gallons = $\frac{DistanceTravelled}{MilesPerGallon}$

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = $\frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}$

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

$NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y$

The sum of the angle measures of a polygon with n sides is 1260. find n.

Murrr4er [49]

Knowing the interior angle sum formula is;

180x(n-2)

180x(n-2)=1260 (solve for n here)
180n-360=1260
180n=1260+360
180n=1620
n=1620/180
n=9

Therefore, this polygon has 9 sides.

Hope I helped :)
