Answer:
As Per Provided Information
We have to use π = 3.14
Diameter of baseball is 3 inch
So, Radius of Baseball will be
Radius = 3/2 inch
Radius = 1.5 inch
we have been asked to determine the surface area of given baseball .
<u>Using </u><u>Formulae </u>
<u>
</u>
substituting the value and let's solve it
<u>Therefore</u><u>,</u>
- <u>Surface</u><u> </u><u>Area </u><u>of</u><u> </u><u>baseball</u><u> </u><u>is </u><u>2</u><u>8</u><u>.</u><u>2</u><u>6</u><u> </u><u> </u><u>sq.</u><u> </u><u>inch</u><u> </u><u>.</u>
So, your answer is 28.26 sq.in

<h3>The variable</h3>
This is the item that is being surveyed.
The surveyed item is birth weights
Hence, the variable is birth weights
<h3>The
units of the variable</h3>
From the question, we have:
Average birth weight is 6 pounds 8 ounces.
Hence, the units of the variable are pounds and ounces
<h3>The population</h3>
This is the total number of babies in Southeast Asia
Hence, the population of interest is the babies in Southeast Asia
<h3>The individual</h3>
This is the people in the survey
Hence, the individual in the study is the 100 babies that were randomly surveyed
<h3>The
parameter of interest</h3>
This is the value that gives the required information.
Hence, the parameter of interest is the average birth weight
<h3>What is the statistic involved</h3>
The statistic is the average
