Answer:
Step-by-step explanation:
In this case the solution of the integral is
[R^{2} - 0]h = \pi R^{2}h](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B2%5Cpi%7D%20_0%20%7B%7D%20%5C%2C%20d%5Cphi%20%5Cint%5Climits%5ER_0%20%7B%5Crho%7Dh%20%5C%2C%20d%5Crho%20%3D%20%5B2%5Cpi%20-%200%5D%28%5Cfrac%7B1%7D%7B2%7D%20%29%5BR%5E%7B2%7D%20-%200%5Dh%20%3D%20%5Cpi%20R%5E%7B2%7Dh)
because h is a constant, and where the expression

was used.
I hope this is usefull for you

Answer:
4 hours 7 minutes
Step-by-step explanation:
Since Trevon takes 10 hours to clean the attic, he cleans 1/10, 10% or .1 of the attic per hour. Since Cody takes 7 hours to clean the attic, he cleans 1/7, 14.3% or .143 of the attic per hour.
Together, that means they clean .1 + .143 of the attic per hour. That's an hourly rate of:
.1 + .143 = .243
The portion of the attic they clean in x hours is .243x. We'd like to know how long it will take them to clean 100% or 1 of the attic. So:
.243x = 1 Divide each side by .243
x = 1/.243
x ≈ 4.115
Let's convert .115 to minutes by multiplying by 60
.115 * 60 = 6.9 round to 7 for 7 minutes
It will take them around 4 hours 7 minutes to clean the attic.
