X=+- the square root of 4

Simplify that

X=plus or minus 2

The answer can be either -2 or +2 (which is just 2)

The formula for finding the volume of a nose cone of an aircraft is V = (pi * d ^ 2 * h)/6 where d is the diameter of the base o

adell [148]

Answer:

$h=\frac{6V}{\pi d^2}$

Step-by-step explanation:

we have

$V=\frac{\pi d^2h}{6}$

Solve for h

That means ----> isolate the variable h

step 1

Multiply by 6 both sides

$6V=\pi d^2h$

step 2

Divide by $\pi d^2$ both sides

$h=\frac{6V}{\pi d^2}$

aliya0001 [1]

Answer:

Step-by-step explanation:

Change mixed fraction to improper fraction. Then reduce to lowest term if possible.
