A circle has a radius of 10. An arc in circle has a central angle of 72 what is the length of the arc

BARSIC [14]

Answer:

4π

Step-by-step explanation:

-A circle subtends a total angle of 360 ° from its center.

-The length of an arc is directly proportional to the angle it subtends from the circle's center.

#The arc's length can therefore be calculated as:

$C=\pi D=2\pi r\\\\\therefore C=\frac{72\textdegree}{360\textdegree}\times 2\pi \times 10\\\\=4\pi$

Hence, the length of the arc is 4π

Solve the system by substitution. -4.5-2y=-12.5 , 3.35x-y=-0.75

goldenfox [79]

First, we solve for y in the first equation:
$-2y = -12.5 +4.5$
$-2y=-8$
$y= \frac{8}{2}$
$y=4$
Then, we substitute the y value in the other equation and solve for x:
$3.35x-(4)=-0.75$
$3.35x=-0.75+4$
$3.35x=3.25$
$x= \frac{3.25}{3.35}$
$x= \frac{65}{67}$
