Option A) 2/3 πx³ is the expression that represents the volume of cone in cubic units.

Explanation:

The general formula for the volume of the cone is given by,

⇒ 1/3 πx²h

where,

  • x is the radius of the base of cone.
  • h is the height of the cone.

It is given that,

Height of the cone is twice the radius of its base.

Therefore, the volume of the cone is represented as

Substitute h=2x in the volume of the cone volume.

⇒ 1/3 πx²(2x)

⇒ 2/3 πx³ cubic units.

Hence, option A) 2/3 πx³ is the expression that represents the volume of cone in cubic units.
