Answer:
19.48 m
Step-by-step explanation:
The formula that is used to find arc length is:
arc length = 2πr 
In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.
arc length = 2 × π × 9 ×
= 2 × π × 9 × 0.3444
= 19.48 m
there's no exact answer for it because pi goes on forever
The three important about the box and whisker plot is that it shows median, LIQ (Low interquartile), UIQ (Upper Interquartile), the lowest and highest number
That would be tan
(1-cos)(1+cos)=1-cos² which equals to sin²
√sin²/cos²= sin/cos which equals to tan
