A cone has a diameter of 6 cm and a height that is 3 times the diameter. Using 3.14 for pi, which of the following can be used t
Zinaida [17]

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Step-by-step explanation:

Given

Diameter of Cone = d = 6 cm

Radius will be:

r = d/2 = 6/2 = 3 cm

Height of cone = h = 3d = 18 cm

The volume of cone is given by:

V = \frac{1}{3}\pi r^2h

Putting the values

V = \frac{1}{3} (3.14)(3)^2(18)

Hence,

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer
