Dano; r1=20cm O02=27cm Найти r2

The problem describes two circles. Given r1 = 20cm and the distance between centers O02 = 27cm. The task is to find r2.

Without further information or a diagram showing the relationship between the circles (e.g., if they are tangent internally or externally, or intersecting), it is impossible to determine a unique value for r2.

If the circles are externally tangent, then O02 = r1 + r2, so 27 = 20 + r2, which gives r2 = 7cm.

If the circles are internally tangent, then O02 = |r1 - r2|. If r1 > r2, then 27 = 20 - r2, which is impossible as r2 would be negative. If r2 > r1, then 27 = r2 - 20, which gives r2 = 47cm.
