What you would use in a 2 step equations is to have more than one operation. Or to do a 2 - step - equation.

You have to simplify a lot of things.

You would use addition or subtraction and then multiplying or dividing.

And finally, you would get the answer for that variable.

For example, 2x+3=3*4

3x+3=3*4

3x+3=12

-3 -3

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

3x=9

x=3

Sav [38]

Answer:

10.12 $m^{3}$

Step-by-step explanation:

Given:

0.07 cm thick = 0.007m and it is dr (the change in radius)

As we know that, the volume of a hemispherical dome with diameter 48 m is:

V = $\frac{2}{3}$ π $r^{3}$

Take the derivative of V we have:

$\frac{dV}{dr}$ = 2π $r^{2}$

<=> dV = 2π $r^{2}$ *dr

<=> dV = 2π* $48^{2}$ *0.0007 = 10.12 $m^{3}$

Hope it will find you well.
