Google Sketch Up Geometry

1) First off we decided to do the length of the slope.sa
2) We figured out that in order to find the slope we need to find the height and the base
3) After studying the shape we figured out that the rise is 1.5m by seeing that the height is 3m then 1.5 is half so another would get us the the place we wanted also indicating that its height is 1.5
4) The run how ever is 3m we saw this because the whole base was 6m while half was 3m and the point where the run was located was half point (plus there was more evidence showing that this was 3m)
5) A^+B^=C^ --> 2.25 +9.00= 11.25=C^ while C would be 11.25 square rooted= 3.35
6) Surface area- Divide object up, number separate Surfaces, calculate each one, add together to find the total m^2
7) We found the volume of the shape by multiplying the width times the length times the height

How to Find the Circumference of a Circle

To explain how to find the circumference of a circle i will show it in steps making it easier to understand it.   

Step 1: Draw a circle and when you do make a triangle within the circle to the have point making this your radius.

Step 2: we are going to calculated the the height and base of the triangle that we have drawn into our circle

Step 3: Could also be in step 2 but this is find the formula of what were trying to do which is this: B*H (base times hight) over 2 

Step 4: We change the B within the formula making it C (circumference) because we are looking for the circumference not the base

Step 5: We notice that Diameter times pie=c So we could also change formula once more making it now: D*pie*r over two. The same exact formula just a little less loose and we also gained a little bit of knowledge knowing what times what equals the circumference 

Step 6: Looking back at step five we see that the diameter is made up of radius times radius (across the circle) then we write this in as r(2)

Step 7: The formula looks like this (the finalized look until we eliminate the two's) 2r*pie*r over 2

as i mentioned above the dimeter is now replaced with 2r

Step 8: We eliminated both of the twos leaving us with r*pie*r 

Step 9: Notice that there are 2 r's so we put both of them together making it r(2)

Step 10: Final step we take the what we got, which is r2*pie and we flip it around because thats the mathematical way its written, but mathematically look at it it really does not matter, giving us our final formula:

Pie*r2
