Day 8: Unit 2                                   Mackenzie Herrington & Mckenzie Neubert
Daily Objective: Volume of prism, pyramid, cylinder, cone, sphere.



Quiz:
1.Sally wants to know how much soda a can with the height of 4in and the radius of 2in can hold.

2. Joe wants to know how much a box with the length of 2ft and the width of 1.5ft with the height of 1ft can hold.

3. Ally wants to know how much air she has to put in her beach ball when it has the 12in.

Answer Key:
1.
22xπ=12.56
  12.56x4=50.24in3

2.
2x1.5x1=3ft3

3.
123xπ÷4x3=4,071in3

Day 7: Unit 2                                    Mackenzie Herrington & Mckenzie Neubert
Daily Objective: Volume of prism, pyramid, cylinder, cone, sphere.
       










 

 Quiz
1) Find the volume of this prism.







2) Find the volume of this sphere.











3) Find the volume of the cylinder.












Answer Key
1) Area of BxH= Volume
6x3=18
18x4= 72
2) 4/3x 3.14x R3=volume of sphere
4/3x3.14x113= 4/3x3.14x 33= 138.16 
3)  Area of BxH= Volume
Base= 42x3.14= 50.24
50.24x(H)12= 602.88
