Answer:
Let the coordinate of focus be 
As per the statement: The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide.
⇒Length of Major axis=base of an auditorium = 200 feet and Length of a minor axis=wide of a auditorium = 100 ft
Semi-major axis (a) = 100 ft and
semi-minor axis(b) = 50 ft
Then, by an equation:

Solve for c:
Substitute the given values we have;

Simplify:

or
ft
Distance between the foci is, 
Therefore, the distance between the foci to the nearest 10th of a foot is, 173.2 ft
Answer:
V = 549.5 ft³
Step-by-step explanation:
The formula for the volume, V, of a cylinder of radius r and length h is
V = πr²h.
Substituting 2.5 ft for r and 28 ft for h, we get the volume
V = 3.14(2.5 ft)²(28 ft), or
V = 549.5 ft³

Answer: 10 π square units
Step-by-step explanation:
The circumference of a circle is given as 2πr
where π = pie
r = radius
Since radius has been given as 5
Circumference= 2πr
= 2 × π × 5
= 10 π units
