Answer:

19.2

76.8

Step-by-step explanation:

density × volume = mass

mass = 62.4 × (pi × (40/2)² × h)

mass = 78,374.4h

WD = m×9.8×h = 9.8mh

WD = 768,069.12h²

At h = 5

WD = 768,069.12×5²

= 19,201,728 ft-lb

= 19.2 million ft-lb

At h = 10

WD = 76,806,9.12 × 10²

WD = 76,806,912 ft-lb

= 76.8 million ft-lb

V=pi r^2 h solve for pi<br><br>please help asap<br>will mark brainliest
kogti [31]

Answer:

\pi=\frac{v}{hr^2}

Step-by-step explanation:

So we have:

v=\pi r^2h

And we want to solve for π.

First, divide both sides by h:

\frac{v}{h}=\pi r^2

Now, divide both sides again by r²:

\pi=\frac{v}{hr^2}

And this is our answer :)

A stone is thrown at an angle of 30° above the horizontal from the top edge of a cliff with an initial speed of 12 m/s. a stop w
stellarik [79]
To solve this problem you must apply the proccedure shown below:
 1. You must apply the following formula:
 yo=-(Voy)t+gt²/2
 2. You have that:
 Voy=VoxSin(30°)
 Voy=(12 m/s)(Sin(30°))
 Voy=6 m/s
 t=5.6 s
 g=9.8 m/s²
 2. When you susbtitute these values into the formula, you obtain:
 yo=-(6 m/s)(5.6 s)+(9.8 m/s^2)(5.6 s)²/2
 yo=120.06 m
 Therefore, the answer is: 120.06 m

Which equation is the result of subtracting the second equation from the first?
rewona [7]

Answer:

the answer is

-x-8y=8

or, x + 8y= -8

Step-by-step explanation:

4x - 6y = 13 - (5x + 2y = 5)

or, 4x - 6y = 13

- 5x - 2y = -5

-------------------------

- x - 8y = 8
