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:
y=1/2x+5
Step-by-step explanation:
first you have to find the slope by using
so when you plot in your points and you will get 1/2x.
then you need to find your y-intercept
and since you don't have a 0 you have to slove by using y=mx+b (slope-intercept) formula
you plug in your points and you will get
b=5 and that is how you get your equation.
