-2f-5=-e
then you divide by the -1 to get the positive e
e=2f+5
6.4/52.032=0.123
52.032/6.4=8.13

Step-by-step explanation:
The radius r is the distance from the centre to a point on the circle.
Use the distance formula to calculate r
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (5, - 3)
r = 
= 
=
