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.

C. Buying a needle and buying a thread are dependent events.
Explanation:
The first statement is incorrect because the given events are dependent on each other because the probability that a customer buys a needle given that the customer buys thread is 0.25.
The second statement is incorrect because we cannot say all those who buy a thread also buy a needle.
The fourth statement is incorrect because the probability that a customer buys a needle and thread is
