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=$\dfrac{1}{3}\times \pi r^2h$

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=$\dfrac{1}{3}\times 3.14\times 5^2\times 10$

V=261.66 in³

Hence, Volume of cone is:

261.66 in³

Answer 2

The radius is 5 so the height ten in.
