Answer 2

Calculation of the distance between the centers of two circles with external tangency

To find the distance between the centers of two circles with external tangency, we can use the following formula:

Distance = Sum of the radii of the two circles

In this case, the radii of the two circles are given as 25 cm and 21 cm. Therefore, the distance between their centers can be calculated as:

Distance = 25 cm + 21 cm

Calculating the sum, we get:

Distance = 46 cm

So, the distance between the centers of the two circles is 46 cm.
