Answer:
Step-by-step explanation:
It is convenient to use a spreadsheet to total the numbers for you. This reduces errors and put the numbers in a form that makes it easy to see what you're working with in any given calculation.
men with HS degree = (male HS)/(all male)
= 76/425 ≈ 0.1788 ≈ 17.9%
__
2-yr degrees that are women = (female 2-yr)/(2-yr total)
= 248/491 ≈ 0.5051 ≈ 50.5%
__
4-yr degrees in group = (4-yr degrees)/(total group)
= 258/925 ≈ 0.2789 ≈ 27.9%

<em>Comment on the problem</em>
The spreadsheet is identical to the one used for your other problem. All that needed to be done was to enter the new numbers. The formatting, headers, and formulas remained the same. For solving these problems, it's a matter of picking the two numbers needed from the appropriate row or column and computing their ratio.
(The computations were done by hand here to better show you the numbers used and the rounding to tenth percent. They can be done in the spreadsheet with point and click.)
The area of a circle is represented by the equation:
We know that the diameter is two times the radius:
So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:
-->
So then we can plug this radius in to the equation for the area of a circle:
We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:
Now we know that the area of this circle is 452.16 square meters.
