A=πr^2s/360 multiply both sides by 360
360A=sπr^2 divide both sides by πr^2
s=360A/(πr^2)
A common tangent is a line that happens to be tangent ("touching but not intersecting a curve or curved surface") to two different coplanar ("in the same plane) circles. I do hope that helped you.
4 + 3(10 - 23)
