The triangle given is right triangle with ratio of sides AC:AB:BC=3:5:4 If 118r is the radius, then by secant-tangent rule "If a secant segment and tangent segment are drawn to a circle from the same external point, the product of the length of the secant segment and its external part equals the square of the length of the tangent segment.", (3-2r)3=1. This gives r=4/3 and hence the radius 157.33

Its a right angled triangle and
ans guess
r=157.33
area=77766.28
