1) True, True, False
Rewritten statement: 46,013.86 cm³ of water was used to fill 40 balloons
2) False, True, True
Rewritten statement: The formula
can be used to find the volume of the model of Earth.
3) True, False, True
Rewritten statement: The volume of all the basketballs is 13,467.62 in³
Explanation:
Question 1
Given:
Substituting the given radius into the formula:
Rewritten statement: 46,013.86 cm³ of water was used to fill 40 balloons
-------------------------------------------------------------------------------------------------------
Question 2
Earth
Given:
- diameter = 4.8 cm ⇒ r = 2.4 cm
Substituting the given radius into the formula:
Rewritten statement:
The formula
can be used to find the volume of the model of Earth.
Saturn
Given:
- diameter = 45.6 cm ⇒ r = 22.8 cm
Substituting the given radius into the formula:
Difference between models= 49,647.02 - 57.91 = 49,589.11 cm³
-------------------------------------------------------------------------------------------------------
Question 3
Given:
Substituting the given values into the formula:
Given:
- diameter = 9.5 in ⇒ r = 4.75 in
- 30 basketballs
Rewritten statement: The volume of all the basketballs is 13,467.62 in³
Empty space in the container = volume of container - volume of basketballs
⇒ 74813.89 - 13467.62 = 61,346.27 in³
