Today, I was finished with everything, so I helped Kayla with finishing her days.

5/23 Update

I finished all my days and turned in all of my work.

Unit 1 Day 4

Unit 1 Day 4 

Using surface area of prism, pyramid, cylinder, cone, and sphere in real life 

Quiz: 

1. Find the surface area of this house:  

      

2. Find the surface area of this book:  

 

   5” 

           

                               10” 

             

2”

   3.) Find the surface area of this ball:  

[Drawing] 

12”   

Answer Key: 

1. 20 x 25 x 2 = 1,000 

20 x 25 x 2 = 2,500 

50 x 10 x 2 = 1,000 

20 x 10 = 200  

4, 700’ squared 

2. 5 x 10 x 2 = 100 

2 x 10 x 2 = 40 

2 x 5 x 2 = 20  

160” squared 

3. 4 x pi x 6 squared 

4 x pi x 36 

12.56 x 36 

452.16” squared  

Unit 1 Day 3

Unit 1 Day 3 

Surface area of prism, pyramid, cylinder, cone, and sphere 

Formulas: 

Prism: area of base + area of sides Pyramid: area of base + area of sides Cylinder: area of base + pi x diameter x height Cone: area of base + pi x radius x slant height Sphere: 4 x pi x radius squared 

Quiz: 

1. Find the surface area of this cylinder:  

[Drawing][Drawing]                      6” 

     8” 

2. Find the surface area of this cone:  

  

     25”  

[Drawing]                    15” 

3.  Find the surface area of this sphere:  

[Drawing][Drawing]     

                 45.6’ 

Answer Key:  

1.  6/2 = 3 squared = 9 x pi = 28.26 x 8 = 226.08” squared 
2. 15/2 = 7.5 squared = 56.25 x pi = 176.625  

Pi x 7.5 = 23.55 x 25 = 588.75  

765.375” squared 

     3.)  4 x pi = 12.56 x radius squared = 6,529.19’ squared

Concept of scale   

(VIDEO)  

Quiz: 

1.) If you are looking at a blueprint of a house and notice the scale is 1 inch is equal to 4 feet, and the bedroom is 22’ x 30’ , how big is the bedroom on the blueprint?  

     2.) Solve for X: X 

[Drawing] 

[Drawing]   5” 

  

 4”                              9” 

        21’ 

[Drawing]    3.) Solve for X 

[Drawing]                4’ 

                                       81’ 

    X 

Answer Key 

1.)     4 = 22        4x=22  

    1     x           x= 5.5”    

    4 = 30        4x=30 

    1     x           x= 7.5” 

     2.)    4 = 9           4x=45  

             5    x             x= 11.25  

     

     3.)   x = 81           21x=324 

            4    21               x= 15.4
