Can someone please explain a few of these so that maybe I can understand it?! Please?! I just don’t get it :( Part A
Which measurements do you need to know to find the volume of a cylinder?

Part B
Since the base of the refraction cup is a half circle, how can you find the radius? What is the radius?

Part C
If you put two refraction cups together, what three-dimensional shape do you have?

Part D
The formula for the volume of a cylinder is v= 3.14r^2h.
What is the approximate volume of two refraction cups use 3.14 for pi.

Part E
Since one refraction cup is half of a cylinder, how could you change the formula for the volume of a cylinder to calculate the volume of a refraction cup?

Part F
Using the equation from Part E, what is the approximate volume of one refraction? What is the relationship between this value and the value from part D? Use 3.14 for pi.
