Phil served 2/8 of an apple pie because in order to have a common denominator, you need to multiply 1/4 by 2/2.
Phil served 2 more pieces of blueberry than apple pie because 1/2(4/4) = 4/8, and 4/8 - 2/8 = 2/8.
Answer:

Step-by-step explanation:
The volume of a cylinder is:

where
is the radius and
is the height.
The height is 4 inches greater that the radius, so:

Substituting this in the formula for volume:

the volume is 
thus:

Dividing everything between pi:


We can see that the solution for this is 
since 
We have the radius, now we find the height:


"how long..." is asking for time (t). "The amount of time spent in the air" is the time from when the ball was kicked (0 seconds) to the time it landed on the ground. Need to find the x-intercepts (one will be negative which will be invalid). You can do this by factoring ... <em>or by using the quadratic formula.</em> With the equation you provided, it is not factorable, so you must use the quadratic formula.
h = -16t² + 60t + 3
a=-16 b=60 c=3





or 
or 
t = -0.05 or t = 3.8 <em>disregard the negative</em>
