2 pi r h+2 pi r squared
2 x pi x 40 x 17 = 4272.566009
2 x pi x 40 squared = 10053.09649
so 4272.566009 + 10053.09649 = 14325.6625

Answer:
a) How much Carl earns an hour? $15/h
b) Who earns more per hour? Carol
c) Graphed
Step-by-step explanation:
a) Carl earns $15 per hour.
Earnings per hour can be rewritten as earnings/per
Or earnings divided by hours.
Take a random pair of time and money earned:
$45/3h = $15/1h
Check it with another pair:
$75/5h = $15/1h
b) Carl earns more per hour.
His earnings can be modeled with the equation y = 15x. For every hour he works, he earned 15 dollars.
Louis's earnings are y = 12x, meaning he earns 12 dollars an hour.
15 > 12
c) See picture
Blue is Carl and red is Louis
