When finding the volume of this shape, there would practically be a formula that we would have to use, in order to solve this on how we are suppose to do.
We know that the radius would then be 4, and therefore, we would just plug this in into the formula which would be illustrated below.
All we would have to do, is to plug the number 4 into the proper location in the formula.
In a decimal form, your correct answer would then be 268.08.
By as we can see above, we would have to convert the decimal form, into a fraction form, and this would be shown below.

Your correct answer should be (option a)

Answer:
0.96 = 96% probability that at least one of them detect an enemy attack.
Step-by-step explanation:
For each radar, there are only two possible outcomes. Either it detects the attack, or it does not. The missiles are operated independently, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Assume that a particular detection system has a 0.80 probability of detecting a missile attack.
This means that
If two military radars are installed in two different areas and they operate independently, the probability that at least one of them detect an enemy attack is
This is when
. So
In which
0.96 = 96% probability that at least one of them detect an enemy attack.
