GED Math Geometry: Volume of Rectangular Prisms, Cylinders, Spheres, Cubes, Cones, and Pyramids

[@theghost3061]

Thank you for your videos, I passed the math GED today!

[@gregbadalian3144]

For GED math, does anyone who has taken the test already know if pi (π) 3.14 is left in a question, like v=16π or is 3.14 always multiplied by, for example, the radius squared for a cylinder? My Kaplan book and a KZbin video by Test Prep Champions seem to differ on this, and I want to be prepared.

[@rajeshmaniram3941]

Thank you so much for not making math so complicated, I have learned so much from your videos.

[@renelemmer538]

Hi Parker! I am writing my math today. I have watched most of your math videos, and I trust that it will go well.

[@shanteperry3029]

I think I need to watch this again and try not to over think it. I understand a little more though. Thanks for your videos!!!

[@loosdamoose4489]

Thank you so much becuase of your channel,I PUNCHED THE MATH EXAM RIGHT IN THE FACE,and passed

[@TestPrepChampions]

Congratulations!!! You're more than welcome!

Congratulations and thanks for watching!

Do we not times the the pie 3.14 times the answers ?

[@Dr.K-vp6fc]

if any volume fill in the blank question invloving pi was asked, do I just fill in the value together with the pi i.e 16pi or do i fill in the total value after multiplication with the pi?

[@TestPrepChampions]

Unfortunately, I don't know the answer to this. Tbh, I've seen it in practice questions just left as the pi symbol and I've also seen it multiplied out. I'd be prepared for either way.

On the cone how did you get 9 from switching r2 with the 3? I’m really confused and would appreciate if you could help me understand better

[@sheachopper6416]

During the official GED test are we required to know all of these formulas or are we given a sheet that tell us? also is the test on computer or on paper?

[@TestPrepChampions]

You will be given all of the formulas, so you don't have to memorize them. You just have to know how to use them. And the test is on a computer.

[@TestPrepChampions]

@S G Why do you say it's useless? You have to use it if you want to get a high score unless you memorize all the formulas, which there's no reason to do.

[@KayBreann-mb5xu]

Going to take my test tomorrow morning pray pass 🤞🤞

[@TestPrepChampions]

Good luck!! Thank you for watching!

My formula sheet says surface area of a cylinder formula is 2(pie)rh+2(pie)r squared. Why is it different from your formula?

[@TestPrepChampions]

It's the same formula. There's no difference other than the order the terms are written in. Mine just has 2(pie)r squared written first. Addition is cumulative, so the order you do the addition doesn't matter. Either will give you the same answer.

[@kidc_7951]

@@TestPrepChampions I mean the number 2 at the beginning of the formula. Does the number 2 represent the top side of the cylinder and the bottom side?

[@TestPrepChampions]

@@kidc_7951 Wait, are you talking about the surface area or the volume? In this video, I show the formula for the volume of a cylinder.

[@kidc_7951]

@@TestPrepChampions I looked at the video again, you found the area of a circle not the surface area of a cylinder. My mistake. Do you have any videos for the surface area? I'm not sure what the 2 stands for. Multiply?

[@TestPrepChampions]

@@kidc_7951 No problem. I don't have a full video on it, but I did an example in my live stream on Friday. And yes, you're right. The 2 just means that you do 2 times pi times the radius times the height and add that to 2 times pi times the radius squared. If you look at my last live stream video: kzbin.info/www/bejne/ap3SloKuoKehjas and skip to about 1 hour and 42 minutes in, I do an example of surface area calculation with a cylinder.

[@michellesutton4395]

When your showing the formula in these why aren't ypu multiplying pii 3.14 ?

[@TestPrepChampions]

Hi, thanks for watching. In some cases you have to multiply by pi, but in others they just leave pi in the answer choices without multiplying. It just depends on which version of the test you get.
