Question 644505
use formula for distance between two points to find the diameter of a circle 

If A({{{3}}},{{{-2}}}) and B({{{7}}},{{{2}}}), then the diameter of a circle is:

*[invoke hummingbird_distance_2D 3, -2, 7, 2]

the area of a circle is {{{A=r^2pi}}}..........since diameter is approximately {{{d=5.65685424949238}}}, then

{{{A=(5.65685424949238)^2pi}}}

{{{A=31.9999999999999977914876780644*pi}}}...round

{{{A=32*pi}}}
