9 inches
The volume of a cylinder is given by ...
... V = πr²h
The least height will be the height that makes the volume exactly that which is necessary.
... 324π in³ = π·(6 in)²·h . . . . . . fill in the given information
... (324π in³)/(36π in²) = h = 9 in . . . . . divide by the coefficient of h
The least possible container height is 9 inches.
Answer:
tan(84)=x/50
Step-by-step explanation:
4x² - 20x + 25
(2x-5)² means (2x-5)(2x-5)
Expand the brackets.
1. do 2x times 2x = 4x²
2. do 2x times -5 = -10x
3. -5 times 2x = -10x
4. -5 times -5 = 25
Altogether it is 4x² - 10x - 10x + 25
This simplifies to 4x² -20x + 25.
Just search it up, anyways the answer is ten.
