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:
A. Split bolt connector.
Explanation:
In order to splice two large wires at a point of server strain, one shall use a split bolt connector of rated for the amperage and voltage of the circuit involved.
The right rating shall avoid accident and ensure safety during handling of the wires.
The wires shall also determine which connector is to be used, for the case of copper, a copper split bolt connector shall be used.
