Question

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?

one over three(3.14)(3cm)2(18cm)
one over three(3.14)(6cm)2(18cm)
one over three(3.14)(18cm)2(3cm)
one over three(3.14)(18cm)2(6cm)

Answer 1

"one over three(3.14)(6cm)2(18cm)" is the one among the following choices given in the question that can be used to calculate the volume of the cone. The correct option among all the options that are given in the question is the second option. I hope that this is the answer that has actually come to your help.

Answer 2

Answer:
`\text{one over three }(3.14)(3cm)^2(18cm)`

Explanation:

The volume of a cone is given by :-

`V=(1)/(3)\pi r^2 h`, where r is radius and h is height of the cone.

Given : Diameter of cone : d= 6 centimeters

Then radius of the cone =
`r=(d)/(2)=(6)/(2)=3\ cm`

Height of the cone :
`h=3d=3(6)=18\ cm`

Now, the volume of the cone will be :_

`V=(1)/(3)(3.14) (3)^2 (18)`
