The diameter of the base of the cone measures 8 units. the height measures 6 units. what is the volume of the cone? a)240 cubic units b)321 cubic units c)48x cubic units d)647 cubic units

  cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

Since you already know that height and  the radius, you can substitute them into the formula. Then, the volume of this cone is:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
