Calculation of the distance between the centers of two circles

To find the distance between the centers of two circles, we can use the formula for the distance between two points in a coordinate plane. Let's assume that the centers of the circles are point A and point B.

The formula for the distance between two points (x1, y1) and (x2, y2) is given by:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, we need to find the distance between the centers of two circles with radii of 7 cm and 4 cm, respectively. Since the circles have an external tangent, the distance between their centers will be equal to the sum of their radii.

Let's calculate the distance:

Distance = 7 cm + 4 cm = 11 cm

Therefore, the distance between the centers of the two circles is 11 cm.

Please note that the search results did not provide specific information for this particular question. However, the calculation is based on the properties of circles and the formula for the distance between two points.
