For a cone, the equation for volume would be
V = π r^2 h/3.

( volume = pi x radius squared x height / 3)

To find the volume for this question, you would set up the equation like this:

V = π x 2^2 x 12 / 3

Then, following the order of operation, you would do the following:

V = π x 4 x 12 / 3

(You get the 4 from 2 squared)

V = π x 4 x 4

(You get the second 4 from dividing 12 by 3)

V = π x 16

(You get 16 from multiplying 4 and 4)

V = 16π

(You get 16π from multiplying 16 and π, and the number is always in front of the π, so you would never get a π16, it would only be 16π)

So, your volume would be 16π, which is answer D.

I hope I helped! c:

Find the inverse of the function.<br> y = x2 + 4x + 4
Eddi Din [679]

Answer:

y = -2+\sqrt{x} and y = -2 - \sqrt{x} combined, or x = y^2 + 4y + 4

Step-by-step explanation:

y = x^2 + 4x + 4

substitute y for x and x for y

x = y^2 + 4y + 4

this is technically the inverse but I will simplify further

x = (y+2)^2

±\sqrt{x} = y+2

y = -2±\sqrt{x}

y = -2+\sqrt{x} and y = -2 - \sqrt{x} combined
