Answer:
24.8 inches
Step-by-step explanation:
Volume of a cylinder=πr²h
Where volume=774 and h=0.4
Now
774=(3.14)r²(0.4)
774=1.2566r²
Divide both sides by 1.2566
r²=615.94
Taking sq root on both sides
r=24.8 inches
3 hours 54 minutes is the answer
They give you the equation for Louis, and the table for Carl. Just find out Carl's equation by dividing the money earned by the time. 45 divided by 3 equals 15. Check it by the next time, 75 divided by 5 equals 15. So Carl's equation is y = 15x. 15x ( Carl's) greater than 12x ( Louis's).
