A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of 2pi/3
Aloiza [94]
You can solve this problem and calculate the arc lenght, by applying the following formula:

 s=θr

 s: it is the arc lenght.
 θ: it is the central angle (θ=2π/3).
 r: it is the radius of the circle (r=10 inches).

 When you substitute these values into the formula, you obtain the arc lenght (s):

 s=θr
 s=(2π/3)(10)

 Then, you have that the value of the arc lenght is:

 s=20.94 inches

Need some help with this question please
Serggg [28]

Answer:

\frac{15}{17}

Step-by-step explanation:

  • \cos( \alpha )  =  \frac{ad}{hip}  \\  \\  \sin( \alpha )  =  \frac{op}{hip}

Pythagorean theorem

hip² = op² + ad²

17² = x² + 8²

x² = 17² - 8²

x \:  =  \sqrt{{17}^{2}  -  {8}^{2} }  \\ x =  \sqrt{289 - 64}  \\ x =  \sqrt{225}  \\ x = 15

\sin( \alpha )  =   - \frac{15}{17}

\sin( -  \alpha )  =  \frac{15}{17}
