Answer:
Option (a) is correct.
The volume of given cone is 72π cubic units.
Step-by-step explanation:
Given : A cone has a diameter of 18 units and height of 8 units.
We have to determine the volume of the given cone.
We know Volume of cone =
Where r is radius of cone
h is the height of cone
Given : diameter = 18units so, radius is half of diameter = 9 units
height = 8 units
Substitute, we have,
Volume of cone =
Simplify, we have,
Volume of cone =
Thus, the volume of given cone is 72π cubic units.
Option (a) is correct.

The scale factor can change how big or small a figure is, though it will still be similar. For example, a triangle with two sides measuring 3 & 3 (isosceles) are scaled in a factor of 6 (becoming larger).
3 x 6 = 18
The new triangle will have the sides measuring 18. Even though the triangles are not congruent, they are similar.
