Answer: I believe his earnings would be 187$ once he teaches 7 classes.
Step-by-step explanation:
$187-$68=$111

$111/17$=$6.5 (round to $7)
(you then plug in the 17 for 7 x ? = 119)

For this case, what we must do is find three times the perimeter of the figure.
The length of the arch is given by:
Where,
r: radius of the circle
alpha: central angle in radians
We have then:
Then, the perimeter of the figure is:
