Question

Select the correct answer.

A cone has a diameter of 18 units and height of 8 units. What is its volume?
A.
727 cubic units
B. 2167 cubic units
C. 6487 cubic units
D. 8647 cubic units

Answer 1

when i do it, with the cone formula w volume, i get 678.567 but that’s none of your choices

Answer 2

The volume of the cone is 678.58 cubic units.

Calculating the volume of a cone.

The volume of a cone can be calculated by using its formula
`V = (1)/(3)\pi r^2 h`. Here, the diameter is 18 units, since radius is half the diameter. Then, the radius = 9 units. Also, the height is given as 8 unit.

Replacing the given parameters into the equation, we have:

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

`Volume = (1)/(3) * \pi * 9^2 * 8`

`Volume = (1)/(3) * \pi * 81 * 8`

`Volume =1 * \pi * 27 * 8`

Volume of the cone = 678.58 cubic units.

Therefore, we can conclude that the volume of the cone is 678.58 cubic units.
