3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

$\frac{3x}{3}$ = $\frac{6}{3}$
3 and 3 cancels out
x = 2

The height of a cone is equal to the diameter of the base. what expression represents the volume of the cone, in cubic units? πx

Basile [38]

The formula for a cone is given as:

V = π r^2 h / 3 ---> 1

Where,

V = volume of the cone

r = radius of the circle base of the cone

h = is the perpendicular length from the center of the base of the cone to the tip at the top

It was given that:

h = d

but d = 2 r, therefore:

h = 2 r

Substituting this to equation 1:

V = π r^2 (2 r) / 3

V = 2 π r^3 / 3

Since r = x, the answer from the choices is:

2πx3
