Step-by-step explanation:
convert feet to inches
9 x 12 = 108
11 x 12 = 132
108 x 132 = 14256
8 x 10 = 80
14256/80 = 178 with a little left over
Consider the attached ellipse. Let the sun be at the right focus. Then perihelion is at right vertex on the x-axis and aphelion is at the left vertex on the x-axis.
The distances:
- from perihelion to the sun in terms of ellipse is a-c;
- from aphelion to the sun in terms of ellipse is a+c.
Then

Add these two equations:
and subtract first equation from the second:
Note that
thus

The equation for the planet's orbit is
