A cone has a diameter of 6 centimeters and a height that is 3 times the diameter. Using 3.14 for pi, which of the following can be used to calculate the volume of the cone? (6 points)

The volume of the cone is calculated by the formula:

V = B*H/3

r=D/2 = 6/3 = 2

where B is surface area of basis and H is height.

B is circle which fomula for surface is:

B = r^2 * pi = 3^2*3,14 = 9*3,14 = 28.26

from condition of height we write:

H = 3*D = 3*6 = 18

now volume is:

If we express all of that in equation of volume we get:

V = 1/3* 3^2*3,14*18

Answer is first option.

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

other answer is correct. i had used the radius of the radius somehow. a website:
