The formula for the volume of a cylinder is
... V = π·r²·h
where r is the radius and h is the height.
Filling in the given numbers, we have
... 225π in³ = π·(10 in)²·h
Dividing by the coefficient of h, we get
... (225π in³)/(100π in²) = h
Cancelling common factors, gives
... 2.25 in = h
The appropriate choice is
... A) 2.25 inches
A)
R'(x)=2*0.0719*x+1.3934
b)
R'(x)=2*0.0719*600,000,000+1.3934
c)
R'(x)=2*0.0719*850,000,000+1.3934

Answer:
(5,6)
Step-by-step explanation:
-6x+6y=6
-6x + 3y =-12
Multiply the first equation by -1
6x-6y=-6
Add this to the second equation
6x-6y=-6
-6x + 3y =-12
---------------------
-3y = -18
Divide each side by -3
-3y/-3 = -18/-3
y =6
Now we need to find x
6x - 6y = -6
6x -6(6) = -6
6x -36 = -6
Add 36 to each side
6x-36+36 = -6+36
6x = 30
Divide each side by 6
6x/6 = 30/6
x =5
