The volume of the balloon is 
Explanation:
The radius of the balloon is increasing at a rate of 3 cm/min.
To determine the volume of the balloon when the radius is 14 cm, we shall use the formula 
The rate of change of r with respect to time t is given by,
Now, we shall determine the 
Now, we shall determine the at 
and substituting , we get,
Thus, The volume of the balloon is

Answer:
(B) Yes, there is reason. The TV audience might not be representative of the population.
(E) Yes, there is reason. Call-in polls tend to be biased.
Step-by-step explanation:
According to the information given we might consider two answers.
The first answer is:
<em>(B) Yes, there is reason. The TV audience might not be representative of the population.</em>
Let's remember that for a sample to be representative of a population must be random and every person must have the same probability of being selected. Here, the question is targeted only to the TV show's audience, so the results can only be interpreted for this segment of the population.
<em>(E) Yes, there is reason. Call-in polls tend to be biased.</em>
The risk is that the people who call might be influenced by the show itself and would not give an unbiased answer. This creates a bias on the sample. Besides, as stated before, not all the elements of the population can be part of the sample.
