Acone has a diameter of 4 centimeters and a height that is 6 times the diameter. using 3.14 for pi, which of the following can be used to calculate the volume of the cone?

The volume of the cone by definition is given by:
 V = (1/3) * pi * r ^ 2 * h
 Where,
 r: radio
 h: height
 Substituting values we have:
 V = (1/3) * 3.14 * (4/2) ^ 2 * (6 * 4)
 Rewriting:
 V = (1/3) * 3.14 * (2) ^ 2 * (24)
 V = 100.48 cm ^ 3
 
 the volume of the cone is:
 V = 100.48 cm ^ 3
 The formula is:
 V = (1/3) * 3.14 * (2) ^ 2 * (24)

and surely you know how much that is.
