Answer:
Equation of circle is 
None of the options is correct
Step-by-step explanation:
Given: Graph
To find: equation of circle
Solution:
A circle is a locus of all points that are at a fixed distance (radius) from a fixed point (centre).
From the graph,
centre (a, b) = 
radius (r) = 4 units
Equation of circle is of form 

Replace w with 10 and solve for a:
10 = (a-7000/2000 + 2)
Subtract 2 from both sides:
8 = a-7000 /2000
Multiply both sides by 2000:
16,000 = a-7000
Add 7000 to both sides:
a = 23,000
You can climb 23,000 feet
The explanation is replacing w with the number of weeks ( 10) and solving for a. You can then check by replacing a with the solution and solving for w.
