8pi ft
Just divide 16 by 2 because it’s half of the diameter
That easy 56.8.895 because when u add all the steps u find u answer so don’t let it fool u
The first triangle does. That's the right answer.
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.
