The diameter of the cylindrical rain barrel which Sophie bought to water her garden, and want to build a platform for it is 15 in.
<h3>What is of volume of cylinder?</h3>Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.
The volume of the cylinder can be given as,
Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.
Sophie bought a cylindrical rain barrel to water her garden, but she forgot to ask the seller what the diameter of the barrel was.
She needs to know the diameter so that she can build a platform for it to sit on.
The seller told her the volume of the barrel is 6,925pi cubic in and its height is 38 in.
The diameter of the cylinder is twice the radius of it. Thus, the diameter of the cylinder is,
Thus, the diameter of the cylindrical rain barrel which Sophie bought to water her garden, and want to build a platform for it is 15 in.

Answer:
- 17.9% of men have a HS degree
- 50.5% of 2-yr degree earners were women
- 27.9% of the group has a 4-yr degree or higher
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.)
