Jim Must Solve a Nonlinear Optimization Problem Where Point a Should

Jim must solve a nonlinear optimization problem where point A should be within a radius of 15 centimeters from each of the points B, C, D, E and F. The decision variables are defined as below.
X = horizontal coordinate of point A
Y = vertical coordinate of point A
The data on the distances is given below: $$\begin{array} { c | c | c } & \begin{array} { c } \text { Horizontal } \\\text { Coordinate }\end{array} & \begin{array} { c } \text { Vertical } \\\text { Coordinate }\end{array} \\\hline \text { B } & 9 & 11 \\\text { C } & 14 & 18 \\\text { D } & 18 & 22 \\\text { E } & 13 & 16 \\\text { F } & 17 & 21\end{array}$$ Formulate a model to find the optimal location of the point A.
