=\frac{43.96}{3}Formula to find the central angle is,

s= r\theta

Where, s = arc length

r = radius

\theta= central angle in radian.

According to the given problem,

r = 7 and \theta = \frac{2\pi}{3}.

First step is to plug in these values in the above formula. So,

s= 7*\frac{2\pi}{3}

=\frac{14\pi}{3} By simplifying.

=\frac{14*3.14}{3} Since \pi =3.14

=\frac{14*3.14}{3}

s=14.65

Hence, arc length iss 14.65 feet.

PLEASE HELP! 40 POINTS
Vedmedyk [2.9K]

I'd start with setting up the equations. Calling x the number of students in most popular country 1, and y in country 2.

x + y = 44740

x - y = 5672

now solve for x1 and x2. You can subtract second from first:

0 + 2y = 39068

y = 19534

so

x = 5672 + 19534 = 25206

Add a sentence to answer it in words.
