This is because irrational numbers are numbers that go on an infinite amount of times and cannot properly be turned into a fraction. A repeating number is a rational number because it can be expressed as a ratio.
Answer:
The volume is 
Step-by-step explanation:
we know that
The volume of the hemisphere ( a greenhouse room) is equal to
In this problem we have
substitute
Answer: 1/6
Step-by-step explanation: To find the probability of rolling a 4, let's use our ratio for the probability of an event which is shown below.
Number of favorable outcomes/total number of outcomes
Since only one side of a number cube has a 4 on it, the number of favorable outcomes for rolling a 4 is 1 and since there are six sides to a number cube and it's equally likely that the cube will land on any of these sides, the total number of outcomes is 6.
So the probability of rolling a 4 is 1/6 which is equivalent
to 0.167 or 16.7%.
That means it is't likely that you would roll a 4 for instance but it's just as likely as rolling any other number.
