ANSWER
E. 10
EXPLANATION
Using Pythagoras Theorem, which says the hypotenuse squared is equal to the sum of squares of the two shorter legs.
Evaluate the squares on the RHS.
Simplify:
Take positive square root.
The hypotenuse is 10 units.
The correct answer is E
The first step is to establish the relationship mass and volume from the data given in the table. This can be done using MS Excel (see attached photo).
From the graph,
y= 0.1174 x
Where y=mass in grams, and x is the volume in cm^3
For x = 15.3 cm^3
Mass = 0.1174*15.3 = 1.7962 g
Rounding off to nearest tenth of a gram,
Mass = 1.8 g
