Question 980044: A cone has a diameter of 6 centimeters and a height that is 5 times the diameter. Using 3.14 for pi, which of the following can be used to calculate the volume of the cone?
1/3(3.14)(30cm)2(6cm)
1/3(3.14)(30cm)2(3cm)
1/3 3.14)(6cm)2(30cm)
1/3(3.14)(3cm)2(30cm)

The formula for the volume of a cone is 1/3 x pi x r^2 x h

The radius is half the diameter. The diameter is 6, so the radius is 3
The height is 5 times the diameter. The diameter is 6, so the height is 30

Plugging these numbers in, along with the value of pi, will give us:
