The base diameter and the height of a cone are both equal toX units.
Which expression represents the volume of the cone, in
cubic units?

1/12πx³

Step-by-step explanation:

Given that :

Base diameter = x

Height, (h) = x

Volume of a cone (V) :

1/3 πr²h

Where r = radius = diameter / 2 = x/2

Hence,

V = 1/3 * π * (x/2)² * x

V = 1/3 * π * x²/4 * x

V = 1/12 * π * x³

V = 1/12πx³

i think this is a open ended question but i agree with other guy who said you should ask it at english section
