| **Two circles with a radius of 10 cm and 6 cm externally touch each other What is the distance between the centers of these circles**

Let there be given two circles with centers O1 and O2 and radii R1 = 10 cm, R2 = 6 cm, respectively. They touch each other at point K. Let’s find the distance between O1 and O2.

The shortest distance from point O1 to O2 will pass through point K, and O1O2 = O1K + KO2. The shortest distance from the center of the circle to point K is the radius of the corresponding circle, O1K = R1, KO2 = R2.

Let’s find О1О2:

O1O2 = O1K + KO2 = R1 + R2 = 10 + 6 = 16 cm.

Answer: the distance between the centers of the circles is 16 cm.
