Since we are solving for h, the equation:
V = πr²h
...divides πr² to the other side. Thus, it becomes....
= h
Which can be rewritten as....
h =
V = πr²h
...divides πr² to the other side. Thus, it becomes....
Which can be rewritten as....
h =
The ladder resting against the house forms a triangle similar to the one in the image below
To answer this question you must use Pythagorean theorem
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = x
b = 4
c = 20
^^^Plug these numbers into the theorem
solve for x
+ 16 = 400
= 384
x = 8√6
or
x ≈ 19.5959....
Hope this helped!
