Question

दोन वर्तुळाची त्रिज्या अनुक्रमे 3 ते 3.5 सेमी व 2.8 सेमी असून ही वर्तुळे परस्परांना स्पर्श करतात तर त्यांच्यात केंद्रातील अंतर काढा​

Answer 1

Answer:

R1 +R2 =6.3 , R1 - R2 = 0.7

Step-by-step explanation:

Here radius of circle are be R1 =3.5 cm , R2 = 2.8

1)

when two circles touching externally the distance between

two centers = R1 + R2 = 3.5 + 2.8 = 6.3 cm

2 )

When two circles touching internally the distance

between two centers = R1 - R2 = 3.5 - 2.8 = 0.7 cm
