End of the Unit


Math- On Friday we learned how to find the surface area of a cylinder.

To find the surface area of a cylinder you need to know 3 different formulas:

A=pie(3.14)*radius(r)2(squared), A=l*w, A=circumferance*w.


!st Step: draw a net of the cylinder.


2: find the radius of one of the circle so you can find the area of it. To find the area, times the radius by itself and times that by pie. Double this answer to have the surface area of both circles.


3:find the surface area of the rectangle. To do this times the diameter of the circle by pie, times that by the width of the rectangle and you have the surface area.


4:add the answer from step 2 and 3 and you have the surface area of a cylinder.
Homework- Page 186 3,4,5,6,7,8,9,10 if you are done you can start the review.


ELA- We started our rough copies on "What makes a true Friend". Remember to type your good copies on the computer and to double space.

  8. Hello (:
    Great job, your post is easy to understand. But you should put "multiply" instead of "times" because I think that's the proper way of saying it. Other than that your post is great.

  9. Great job! It was understandable and your picture was very clear. Well done. Although you could try adding more color or something to make it look more interesting. Other than that, your post was really good.

  10. Awesome Job on your post! I remember that we did something like this! Instead of finding the cylinder, we find like the circumferance of a circle, or a diameter. Anyways you should try to like, add some color to it to make it stand out! Awesome job once again!

  11. great job on your post, you explained it pretty well but if you added pictures as you explained it it would show people how you got it instead of just telling them, other than that great job your picture at the top rocks.
