Last Blogging on Blogging

Well, let me be the first to say this:

It was Joyce who told Mr. Kuropatwa to do this.

Anyways, you can't change the past, you can only survive it. It has been a long five months, but this class is coming to an end. . . thank God. Anywhooo, as my last blogging on blogging will be on what I found easy and difficult.

Well, I found everything easy in this class. Sure, there were difficult questions here and there, but I solved through them.

I think for the things I found difficult, the only two things that come to mind are:

1) When do you have to convert ratios to have the same units?

2) Converting Imperial to Metric.

Other than that, I'm all good! I just have to remember the formulas however :\



Triangle: P = a+b+c
Rectangle: P = 2 (L+W)
Square: P = 4s
Circle: C = πd OR C = 2πr


Triangle: A = 0.5bh
Rectangle: A = LW
Square: A = s2
Circle: A = πr2
Parallelogram: A = bh
Trapezoid: A = 0.5(Base 1 + Base 2)h


Rectangular Solid: SA = 2WH+2LW+2LH
Sphere: SA = 4πr2
Cone: SA = πrs (Slanted Sides Only)
Cylinder: SA = 2πrh+2πr2
Pyramid: SA = Area of Base + Perimeter of Base x Slant Height


Rectangular Solid: V = LWH
Sphere: V = (4/3)πr3
Cone: V = (1/3)πr2h
Cylinder: V = πr2h
Pyramid: V = (1/3)b2h

This was my very last Blogging on Blogging! I had fun in our Math Class! Good luck to everyone on the exam! =D

Its Joyce!

Hehe, well only one question for you ;D

What do you think is your strongest unit throughout the semester?

James said...


But seriously, I think maybe the spreadsheets slightly. I was really strong in all of the units, but maybe a little more in Spreadsheets.

Thanks for the question, lol >_>

Hi there James,

Thanks for collecting all the formulas in one place so neatly!! That is useful to your classmates and your readers I'm sure!

It's good to hear that you did not find consumer math too difficult. Since that is so, I'm wondering why it's been a "long five months"?

Best to you,
