Question

Find what angle MPQ is, if the arc is 9 and the radius is 5

Answer 1

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

Answer 2

that makes no sence

Answer 3

That really doesn't make any sense.

Answer 4

Sorry I messed it up hang on.

Answer 5

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
