The equation of a circle is: (x - h)² + (y - k)² = radius² where (h, k) is the center. Now just plug in your given information and simplify.
(x - 2)² + (y - 0)² = 9²
Your equation is:
(x - 2)² + y² = 81

This question should be relatively easy for a high schooler...
Step-by-step explanation:
d = rt
divide t
d/t = r
r = d/t
Cot(-x) = 1 / tan(-x)
Tan(-x) * 1 / tan(-x) = 1
