How long is the arc intersected by a 2pi/3 radian central angle in a circle with radius 7 feet?
VashaNatasha [74]

=\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.

How do i solve for y and x?
Akimi4 [234]

Answer:

You use the facts about a 30, 60, 90 triangle.

Step-by-step explanation:

The angles in a triangle add up to 180.

90+30+x=180

120+x=180

x=60

This is a 30-60-90 right triangle.

The side opposite the 30 degree angle is a.

The side opposite the 90 degree angle (hypotenuse) is 2a.

The side opposite the 60 degree angle is a\sqrt{3}

We know the side opposite the 90 degree angle.

2a = 12\sqrt{3}

Divide by 2.

a=6\sqrt{3}

a is the side opposite the 30 degree angle (y)

Because we know a, we can find a\sqrt{3}.

6\sqrt{3 } (\sqrt{3})

The square roots cancel, leaving 3.

6 times 3 is 18.

Therefore, the side opposite the 60 degree angle (x) is 18.
