How fast is the area of the spill increasing when the radius of the spill is 18 inches is d) 90pi in ^2/min.
<h3>Area of the spill</h3>
Area of the spill=S=πr²
dS/dr=(πr²)=2πr
Radius change with speed=dr/dt =2.5(m/s)
Area of the spill will increase with speed
dS/dt = dS/dr × dr/dt =2πr ×dr/dt
=2π×18×2.5
=282.74m²/s or 90pi in²/min
Therefore the correct option is D.

Answer:
B Glycolysis occurs in both prokaryotic cells and eukaryotic cells.
Explanation:
The scenario that best supports the claim that organisms of different domains share a common ancestor is option B.
This is because glycolysis occurs in both prokaryotic and eukaryotic cells.
Recall that a prokaryote cell is a cell that does not have well defined nucleus and are unicellular while eukaryotes have well defined nucleus and are multicellular.
Therefore, because glycolysis occurs in both, it suggests that they share a common ancestor.
