Answer:
Option D
Step-by-step explanation:
If the whole grid is considered to be 1,
Each small grid will value = 
There are 72 shaded grids which represent the hundreds = 0.72
When these grids have been divided into 9 equal rows, number of grids in each row = 8
And the value of 8 grids in each row = 0.01 × 8 = 0.08
So the equation is,
0.72 ÷ 9 = 0.08
Therefore, equation represented by the model will be Option (D).
Ah clever. So you need two formulas.
1) Volume of the marble.
4(pi)r^3/3
= 4(pi)(1.4)^3/3
<span>= 11.49 (approx)
</span>
2) Formula for density.
D = M / V
= 9 / 11.49
= 0.78
0.78 < 1
Therefore the marble will float.

Answer:
=760
Step-by-step explanation:
Area: 
diameter= 44
radios= 22
area of full circle:
3.14(22)^2
= 1519.76
Area of half circle"
1519.76/2= 759.88
=760
