<span>The Volume of a Cylinder  =   </span><span>π <span>• r² • height<span>
</span></span></span>radius = 13.5 feet
volume = PI * 13.5^2 * 4 feet (the problem states it is to be filled to a depth of 4 feet)
volume = PI * 182.25 * 4
volume = <span> <span> <span> 2,290 cubic feet</span></span></span>
The hose delivers 80 <span>cubic feet per hour so it will take:
</span>2,290 / 80 = <span> <span> <span> 28.625 </span> </span> </span> hours
**************************************************************************
The volume of the pool is:
volume = PI * 182.25 * 4.5
= <span> <span> <span> 2,576.</span></span></span>5 cubic feet

4/12 <em>= </em>0.33

4/6<em> = </em>0.66

Making <u>4/12</u> less than 4/6.

Your parabola has the form ax^2+bx+c
if a>0 then it is open towards the positive y direction, for a<0 towards the negative y direction
This also means that with a>0 a global minimum exists and for a<0 a global maximum
So by changing a from a>0 to a<0 the parabola previously had a maximum and now has a minimum instead, which is the first option.
