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:
$9 I think

To determine the scale both measurements must be in the same unit, either feet or meters. 1 meter = 3.28084 feet525 meters = 1722.441 feet Scale is 4.2 / 1722.441, or 0.00243839992 1 foot = 0.3048 meters4.2 feet = 1.28016 meters 1.2801 / 525 = 0.0024389992
Hope This Helped :)
<span>False. The surface area formula for a right cone is not the same as
the surface area formula for an oblique cone. </span>
