Some of the questions that we did was:
So Mr.Harbeck gave us a circle that has a radius of 16.5 cm.
The next step for us to do was to find the diameter.
The formula to find the diameter is:
If the image is hard to see or it doesn't work it is:
d= 33 cm
So the next thing we had to find out the circumfrence:
If you don't know what circumfrence is, it is this:
The formula to find the circumfrance for this question is:
The next thing we had to do is find the area of this circle:
The formula to find area is
Once I demonstrated that to you, I will not post any more pictures.
Another circle we did is one which has a diameter of 15.
For us to find the Radius of a diameter the formula is
After we find the Radius we should find the circumfrance(we already have the diameter)
After the circumfrence the last thing we have to do is to find the area.
Another thing we did in class today was we used a cylinder such as this.
After we break it down it should be like this
Since we have the radius we should go onto the diameter
After the diameter, we should go onto the circumfrence:
After circumfrence we should go to Area.
Another formula we did to make everything shorter that I put up there was
So one of the questions that I'm going to be doing is:
Since it gives us the diameter, I started off with the radius.
Then I went to the Circumfrence:
After that, I went to the area:
Another question is:
There is already the radius so you don't bother with that
Next we do the Area
Another Question is:
