Question

A cone has a diameter of 10 inches. If its height is twice its radius, about what is the volume of the cone in cubic inches? Use 3.14 for π.

Answer 1

Answer with Step-by-step explanation:

The volume of cone is given by:

V=
`(1)/(3)* \pi r^2h`

Where r is the radius of cone and h is height

r=d/2 where d is the diameter

Hence, here r=5 in.

height is twice its radius ⇒ h=10 in.

V=
`(1)/(3)* 3.14* 5^2* 10`

V=261.66 in³

Hence, Volume of cone is:

261.66 in³
