The volume of the cylindrical candle that has a base area of 12.56 inches is 12.56h inches³.
<h3>Volume of of cylinder</h3>
volume of a cylinder = πr²h
where
Therefore,
volume of a cylinder = πr²h
Area of the base = πr²
Therefore,
Area of the base = 12.56 inches²
volume of the cylindrical candle = 12.56h inches³

Answer:
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
Step-by-step explanation:
As the test is targeted to 18-to-29-year-old adults using social media, we want to know the probability that a randomly selected adult uses social media and belong to the study group.
To achieve this, we have this data:
- 36% of all adults do not use social media
- 75% of all adults are >30 years old.
- The percentage of population that is <em>either</em> 18-29 years old <em>or</em> uses social media is 66.7%
Using the last data we have that

The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
It would be by -75% since it’s decreasing
