Let d(x) = 2x - 4

Or

y = 2x - 4

We have replace x = y

x = 2y - 4

Now Isolate "y"

x + 4 = 2y

Pass "2" dividing

(x + 4) / 2 = y

y = x/2 + 2

Or

d(x)^-1 = x/2 + 2

MariettaO [177]

Answer:

the volume of the cylinder is 904.32 m³

Step-by-step explanation:

Volume of a cylinder is $\pi r^{2}h$
