Find the distance between the two points in simplest radical form.<br> (-1,0) (8,-5)
ivanzaharov [21]

~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-1}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-5})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[8 - (-1)]^2 + [-5 - 0]^2}\implies d = \sqrt{(8+1)^2+(-5)^2} \\\\\\ d = \sqrt{81+25}\implies d = \sqrt{106}

1. radius = 7 ft, central angle = 18°<br> Find arc length.
Vlada [557]

Answer:

2.2 ft ( to 1 dec. place )

Step-by-step explanation:

The arc length is calculated as

arc = circumference × fraction of circle

     = 2πr × \frac{18}{360}

     = 2π × 7 × \frac{1}{20}

     = 14π × \frac{1}{20}

     = \frac{14\pi }{20} ≈ 2.2 ft
