Given : दोन वर्तूळाच्या त्रिज्या अनुक्रमे 3.5 सेमी व 2.5सेमी असून, ही वर्तूळे परस्परांना आतून स्पर्श करतात
The radii of the two circles are 3.5 cm and 2.5 cm respectively .These circles touch each other from the inside,
To find : the distance between centers.
केंद्रातील अंतर
Solution:
Circle touches each other at Point A
Draw tangent PA
Let say O and O' are center point of circle
Then ∠OAP= 90° and ∠O'AP = 90°
Hence OO'P are colinear point
Distance between OO'
= | OP - O'P|
= | 3.5 - 2.5|
= 1 cm
केंद्रातील अंतर = 1 सेमी
distance between centers. = 1 cm
