## anonymous 5 years ago Find what angle MPQ is, if the arc is 9 and the radius is 5

If the arc length is 9 and the radius is 5, then --> pi*5*2*x = 9 x = .9*pi degrees

2. anonymous

that makes no sence

3. anonymous

That really doesn't make any sense.

Sorry I messed it up hang on.

Okay so let g be the ratio of the arc to the entire circle. a is the angle, so g = a/360 Then, $9 = 2\pi*r*g$ $9 = 2*\pi*r*a/360$ $a = 9/(10*\pi) * 360$ = 103 degrees

thank you
