Question

Select the correct answer A cone has a diameter of 18 units and height of 8 units. What is its volume CA 72 cubic units OB 216 cubic units oc 6-3ncubicunits D. 85 cubic units

Answer 1

B. 216π cubic units

Step-by-step explanation:

Given a cone with radius, r and a height, h:

`\text{Volume}=(1)/(3)\pi r^2h`

• The diameter is 18 units, therefore, the radius = 9 units.

,

• Height, h= 8 units.

Substitute these into the formula:

`\begin{gathered} V=(1)/(3)*\pi*9^2*8 \\ =216\pi\text{ cubic units} \end{gathered}`

The correct choice is B.
