Theres information missing in the question. There should be one more pair of coordinates
Answer:
The solutions are:

Step-by-step explanation:
We have the following quadratic equation

We can rewrite the equation as follows

Now we use the quadratic formula to solve the equation
For an equation of the form
the quadratic formula is:

In this case:

Then:





To the nearest inch it'll be
d×3.14=63
= 20 inches
4.93
^ This number is less than 5, so we round down to 4.9.
