Two circles with radii 3 cm and 4 cm are externally tangent. What is the distance between their centers? (2022)

Step 1: Identify the radii of the two circles. The first circle has a radius of 3 cm, and the second circle has a radius of 4 cm.
Step 2: Understand that when two circles are externally tangent, they touch each other at one point without overlapping.
Step 3: To find the distance between the centers of the two circles, you need to add their radii together.
Step 4: Calculate the sum of the radii: 3 cm (radius of the first circle) + 4 cm (radius of the second circle) = 7 cm.
Step 5: Conclude that the distance between the centers of the two circles is 7 cm.
