In its simplest form, Torricelli's law states that water in a tank will escape through a (small) hole in the bottom with the same speed that it would attain falling from the same height to the level of the hole. ... velocity, g is the acceleration due to gravity, and h is the height of the fluid in the container. Hope that helps!

Answer:
1π
Step-by-step explanation:
suppose the radius of semicircle P is r,
then the radius of semicircle Q = (r+d)/2 ... d≤r
radius of semicircle R = (r-d)/2
area P = 1/2 (r)²π
area Q = 1/2 ((r+d)/2)² π = 1/8 (r² + 2rd + d²)π
area R = 1/2 ((r-d)/2)² π = 1/8 (r² - 2rd + d²)π
shaded area = P-Q-R = 1/2 r²π - 1/4 (r² + d²)π
= ((r² - d²)/4) * π
because there is no constant r value in the question and d value changes with the r change, when the vertical segment length equal the semicircle P radius (r), r=2 and d = 0
therefore the shaded area = ((2² -0²)/4)*π = 1π
Answer:
$45
Step-by-step explanation:
- A deposit is positive, so the integer will be positive.
- An integer is a whole number that's not a fraction, so a positive integer for 45, would be 45.
I hope this helps!
The perimeter because the fence goes AROUND the yard, not in it.
P = 2w + 2l
P = 2(60) + 2(20)
P = 120 + 40
P = 160
Charlene needs 160 meters of fencing material.
